This is with the Ximian SuSE Linux Enterprise Server 9 RPMs for mono
1.0.5.

Wine being sensitive to memory layout is a well documented problem, and
will crash with various security patches installed.
Of course, I was not suggesting that mono fails for all, or even most
users of 2.6.10, surely someone would have noticed before me. I would
love suggestions of where to look, however, as hundreds of other
binaries are all running without a hitch, and the production build is
not very debugger friendly.
For those who might be interested, attached is the output of strace32.
It seems like the process is dying during initial load/link. This is
running '/usr/bin/mono /usr/lib/mono/1.0/mcs.exe' with no arguments.
Am I correct? Is my distribution broken?
Thanks,
