Hi I get the following while trying to compile a mono app: ** ERROR **: file exceptions-x86.c: line 418 (x86_unwind_native_frame): assertion failed: ((how == 0) || (how == 1)) aborting... /usr/bin/mcs: line 2: 9560 Trace/breakpoint trap /usr/bin/mono /usr/bin/mcs.exe "$@" make[2]: *** [Configuration.dll] Error 133 what does it mean? cheers
