Re: Base NSScanner/GSFormat issues - segmentation fault

[Riccardo Mottola]

Hi all, hi Fred.

I went further. I disabled all optimizations and rebuilt whole base. (Is 
there any easier way than editing config.make manually?)

I get now this fat stacktrace:

Program received signal SIGSEGV, Segmentation fault.

And, most importantly, I just installed libobjc2 from GIT!


I somehow remember this issue, do you Fred?
