[Mono-dev] illegal instruction

[Kirby Zhou]

More clearly, the problem maybe lives inside 'mono-2.4.3/mono/*'.

diff -ruN mono-2.4.2.3 mono-2.4.3 > x.patch
cd mono-2.4.2.3
filterdiff x.patch -i ''mono-2.4.3/mono' | filterdiff-x
'mono-2.4.3/mono/tests/*' | patch -p1
./configure
make

And the same error messages appears.

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
