Failure to launch apps - segfault in NSTimer

[Riccardo Mottola]

Hi,

on the following setup:
- Gentoo Linux
- x86
- libobjc2 (latest git)
- latest base/gui/back


A launch of Ink does:

Program received signal SIGSEGV, Segmentation fault.
0xb7561fc8 in -[NSTimer
initWithFireDate:interval:target:selector:userInfo:repeats:]
(self=0x84cb9f4, _cmd=0xb784e4d0 <objc_selector_list+552>, fd=0x0, ti=30,
    object=0x84cb8d4, selector=0x0, info=0x0, f=1 '\001') at NSTimer.m:119
119       if (ti <= 0.0)



what is fd in the signature, which is null?

119       if (ti <= 0.0)
(gdb) list
114                      target: (id)object
115                    selector: (SEL)selector
116                    userInfo: (id)info
117                     repeats: (BOOL)f
118     {
119       if (ti <= 0.0)
120         {
121           ti = 0.0001;
122         }
123       if (fd == nil)

still, none of these looks wild, except, perhaps
