[amd64] Segfault when MCS is running
Last modified: 2012-07-09 11:30:06 UTC
---- Reported by max@duempel.org 2007-01-09 04:28:58 MST ---- When I compile a big library part of the SunUO project (http://www.sunuo.org/), Mono crashes with a segmentation fault. It looks like the faulty code is in the GC. I am using Mono 1.2.2.1-1 (Debian package) on AMD64. max@rabbit:~/svn/sunuo$ make mcs -define:MONO -debug -lib:build -target:library -out:build/scripts/legacy.dll -lib:build -r:System.Web.dll -r:System.Data.dll -r: log4net.dll -r:SunUO.exe -recurse:'scripts/legacy/*.cs' scripts/legacy/Commands/Docs.cs(357,30): warning CS0612: `Server.ScriptCompiler.Assemblies' is obsolete scripts/legacy/Engines/BulkOrders/SmallBulkEntry.cs(76,25): warning CS0612: `Server.Core.BaseDirectory' is obsolete Stacktrace: at (wrapper managed-to-native) System.Object.__icall_wrapper_mono_array_new_specific (intptr,int) <0x0000b> at (wrapper managed-to-native) System.Object.__icall_wrapper_mono_array_new_specific (intptr,int) <0xffffffff> at System.Collections.ArrayList..ctor () <0x0001b> at Mono.CSharp.Convert.FindMostSpecificSource (System.Collections.IList,Mono.CSharp.Expression,bool) <0x0007d> at Mono.CSharp.Convert.GetConversionOperator (System.Type,Mono.CSharp.Expression,System.Type,bool) <0x0039f> at Mono.CSharp.Convert.UserDefinedConversion (Mono.CSharp.EmitContext,Mono.CSharp.Expression,System.Type,Mono.CSharp.Location,bool ) <0x0012c> at Mono.CSharp.Convert.ImplicitUserConversion (Mono.CSharp.EmitContext,Mono.CSharp.Expression,System.Type,Mono.CSharp.Location) <0 x00036> at Mono.CSharp.Convert.ImplicitConversionExists (Mono.CSharp.EmitContext,Mono.CSharp.Expression,System.Type) <0x00059> at Mono.CSharp.Invocation.IsApplicable (Mono.CSharp.EmitContext,System.Collections.ArrayList,int,System.Reflection.MethodBase) <0x 0016d> at Mono.CSharp.Invocation.IsApplicable (Mono.CSharp.EmitContext,Mono.CSharp.MethodGroupExpr,System.Collections.ArrayList,int,Syste m.Reflection.MethodBase&) <0x00036> at Mono.CSharp.Invocation.OverloadResolve (Mono.CSharp.EmitContext,Mono.CSharp.MethodGroupExpr,System.Collections.ArrayList,bool,M ono.CSharp.Location) <0x0050a> at Mono.CSharp.Invocation.DoResolve (Mono.CSharp.EmitContext) <0x00497> at Mono.CSharp.Expression.Resolve (Mono.CSharp.EmitContext,Mono.CSharp.ResolveFlags) <0x001de> at Mono.CSharp.Expression.Resolve (Mono.CSharp.EmitContext) <0x00028> at Mono.CSharp.ExpressionStatement.ResolveStatement (Mono.CSharp.EmitContext) <0x0002c> at Mono.CSharp.StatementExpression.Resolve (Mono.CSharp.EmitContext) <0x00037> at Mono.CSharp.Block.Resolve (Mono.CSharp.EmitContext) <0x00288> at Mono.CSharp.Block.Resolve (Mono.CSharp.EmitContext) <0x00288> at Mono.CSharp.EmitContext.ResolveTopBlock (Mono.CSharp.EmitContext,Mono.CSharp.ToplevelBlock,Mono.CSharp.Parameters,Mono.CSharp.I MethodData,bool&) <0x00284> at Mono.CSharp.EmitContext.EmitTopBlock (Mono.CSharp.IMethodData,Mono.CSharp.ToplevelBlock) <0x00072> at Mono.CSharp.MethodData.Emit (Mono.CSharp.DeclSpace) <0x001c5> at Mono.CSharp.Method.Emit () <0x00021> at Mono.CSharp.TypeContainer.EmitType () <0x00306> at Mono.CSharp.RootContext.EmitCode () <0x002b3> at Mono.CSharp.Driver.MainDriver (string[]) <0x00daf> at Mono.CSharp.Driver.Main (string[]) <0x00064> at (wrapper runtime-invoke) System.Object.runtime_invoke_int_string[] (object,intptr,intptr,intptr) <0xffffffff> Native stacktrace: /usr/bin/mono [0x56b37b] /usr/bin/mono [0x54afc4] /usr/lib/debug/libpthread.so.0 [0x2ab8131f8410] /usr/bin/mono [0x511521] /usr/bin/mono [0x510c08] /usr/bin/mono [0x519901] /usr/bin/mono [0x5194f2] /usr/bin/mono [0x51a4f6] /usr/bin/mono [0x51a774] /usr/bin/mono [0x50ee2a] /usr/bin/mono [0x5183b3] /usr/bin/mono [0x515c36] /usr/bin/mono(mono_array_new_specific+0xdd) [0x4de2ff] [0x40018480] Debug info from gdb: (no debugging symbols found) Using host libthread_db library "/usr/lib/debug/libthread_db.so.1".

This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= make: *** [build/scripts/legacy.dll] Aborted ---- Additional Comments From lupus@ximian.com 2007-01-09 08:22:33 MST ---- I downloaded version 0.4.3 and it built fine in my amd64 box with mono from svn (built three times). Please try building with mono from svn and provide more info about your system (is it an SMP box?). ---- Additional Comments From max@duempel.org 2007-01-09 08:26:29 MST ---- My machine is an AMD Athlon64 dualcore, running with Linux 2.6.19.1 (SMP enabled). It segfaults "most of the time"; when I retry several times, chances are good that compilation succeeds. ---- Additional Comments From lupus@ximian.com 2007-01-09 08:40:51 MST ---- Please try a mono build from svn so we can also get decent backtraces with proper debugging symbols.
