I don't think the crash has anything to do with PIC vs no PIC, as it  
happens during the symbol reading. I don't know what does cause it  
though, and I've never heard of or seen this before. Did you rebuild  
all of your units using the new compiler?

Also, you could try using dwarf (-gw) instead of stabs (-g) debug  
information, as stabs is deprecated by Apple on Mac OS X. The downside  
is that some things don't still completely work with dwarf (e.g.  
shortstrings are truncated at 8 characters).

Another thing you could try is using a different version of gdb (if  
you're using the one from Xcode 2.5, try the one from Xcode 3.0 and  
vice versa; or download the iPhone SDK beta and use the gdb included
