Re: NSString retain crash

[Ivan Vučica]

Hi,

Just a bit of information collecting:
- which version of GNUstep Base are you using (or, which svn revision if 
applicable)?
- which runtime are you using (gcc libobjc, libobjc2, or something else) and 
which version (or svn revision)?
- which compiler and version?
- which OS (a Linux-based OS, or a BSD, or something else)? 
- if you are not using latest svn revision of GNUstep Base, did you try that?

Info above may help someone reproduce the problem or suggest a fix. Looks nasty 
to me, but is probably easy to fix.

Regards,

Ivan Vučica
