Cause of crash

Hi, I am trying to get rc1 up and running on a sarge distro, this gdb session should sum up the problem:

(gdb) run

Trouble is I do not know where to go from here. Apparently the problem is at a low level in wxWidgets. Now I did compile this myself **but** I have compiled and run the 'controls' demo in the wxWidgets samples directory, and that works fine. Note that codeblocks gets as far as displaying correctly the splash screen before it segfaults.

Tips & tricks anybody?

Thanks.

Yop, this bug is fixed yet. You should try downloading and compiling from CVS (or wait for RC2 ). Or remove fno-ppc-struct-return (or something like that, I don't remember exackly) compile option and rebuild C::B.

This week we'll release RC2, we've fixed a lot of those.

Ouch. I got myself a snapshot of the CVS and after a lot of struggling with the bootstrap (actually my autoconf was broke) finally got it compiled up and running.

I was just coming back here to report success and suggest that perhaps it was time for a RC2 when I saw there had been another post.........

Life on the bleeding edge ;-)
