A Debian user reported to me that all Mono applications crash on his AMD64

First we could not find the exact cause, thought it might be a randomizer (like
selinux or grsecurity) or his hardware as nobody could reproduce it.

A 2. user who could reproduce this crash give me the info that it only happens
when running inside an emacs shell. kangaroo on IRC could reproduce it, thus I
filing this bugreport now.

Here how the crash looks like:
$ mcs hello.cs

** ERROR **: file mini-exceptions.c: line 994 (mono_setup_altstack):
assertion failed: (gaddr == tls->stack_ovf_guard_base)

$ mono hello.exe

On Linux/x86 with emacs21 and emacs22 I could not reproduce this crash.

Here the full bugreport at debian:
