Re: NSString retain crash

[Luboš Doležel]

Hi,

- gnustep-base 1.2.40 (Gentoo -r1)
- libobjc2 1.6.1
- clang 3.1
- Gentoo Linux
- not yet, I'll do that

With the old GCC ObjC runtime, the same code says "NXConstantString 
doesn't recognize retain" and it crashes as well. I don't think that's 
correct either, but the new runtime is what bothers me more.
