Description of Problem:
Tried to use Mono from git (commit 00706612686733a2f0aa45f3d2aab9d3a0a38916) on
ArchLinux x86_64 with SGen and pthread.
There seems to be a problem when pthread are used with SGen, and I've got the
same problem on FreeBSD which natively uses pthread.
The problem is not only for x86_64 arch, it's also on x86 FreeBSD, so I guess
that using an ArchLinux x86 with a fresh mono from git will produce the bug.

Steps to reproduce the problem:
1. use an ArchLinux x86(_64) or FreeBSD i386(x86_64) VM
2. clone mono.git
3. ./autogen.sh --prefix=/usr --sysconfdir=/etc --with-libgdiplus=installed
4. sudo make install
5. MONO_ENV_OPTIONS=--gc=sgen mono --verbose /usr/lib/mono/2.0/gmcs.exe

Actual Results:
$ MONO_ENV_OPTIONS=--gc=sgen /usr/bin/mono /usr/lib/mono/2.0/gmcs.exe --version
Stack overflow: IP: 0x544484, fault addr: (nil)
At Unmanaged

Expected Results:
$ /usr/bin/mono /usr/lib/mono/2.0/gmcs.exe --version
Mono C# compiler version
