Well, I patched my kernel with the exec-shield patch, but couldn't make
mono to crash, so I can't find out what's happening :(. Anyway, your
patch has been checked in, so marking this fixed.

+malte, torkar: can you check if just adding PROT_EXEC to the mmap call
+is enough? Doing another syscall is expensive, and it should really be
+no different. Still, this is weird, since we don't execute code from
+the PE binaries: there must be some other bug (maybe in RH's kernel).
+Do you get the same backtrace for the segfaults as Raphael? Can you
+print in gdb the variables accessed on the segfault line (method->name
+and klass)?
