Please fill in this template when reporting a bug, unless you know what you
are doing.
Description of Problem:
"mono --debug" dumps core.

Steps to reproduce the problem:
1. Compile mono 1.1.7 on Solaris.  I used the following:

ld: Software Generation Utilities - Solaris Link Editors: 5.10-1.477
GNU nm 2.15
GNU ar 2.15
gcc (GCC) 3.4.3

2. Run a program, any program, with "--debug."

Actual Results:
>mono --debug lib/mono/1.0/gacutil.exe
Bus error (core dumped)
>mono --debug test.exe
Bus error (core dumped)

How often does this happen? 
Every time.

This is because of lines like this in mono-debug.c:

	* ((gpointer *) ptr) = klass;
	ptr += sizeof (gpointer);

This will crash on machines which do not allow unaligned access
(like the sparc), and it will be slow on machines that allow it
(x86).

This patch should fix the issue -- at least for this access. I haven't
gotten a chance to actually run this on a sparc box. I left the READ
version of the macro in there as it could potentially be useful for
that file.

This happens on IA64 too. Having unaligned accesses is slow even on
architectures which tolerate it like x86. Also, some data structures
inside the symbol file are not aligned properly, like the 
minfo->lexical_blocks structure.

Martin, could you take a look at this ?
