Hi Upgrading to beta 1 does not fix my problem with 0.31: ** ERROR **: file exceptions-x86.c: line 344 (x86_unwind_native_frame): assertion failed: ((how == 0) || (how == 1)) every time I run mono, it fails with that assertion and finishes. This is on suse 9.0, with the RPMs, and as I said, it also happened with 0.31. Any idea? cheers
