David, Maybe we need to start with some basics, because testing by the FBtoC team does create not a crash at this point. I just ran a simple test through gdb and all went fine. Would you compile your test app that fails with FBtoC and use no optimization, and full debug ( names and line# ). Turn off code stripping and run for target 'current mac'. Run the app and get the crash. Check the crashreporter log and see where it crashes. This might be the same thing you sent in the gdb window but it might shed some light. Symptoms still seem to point to an issue related to using ( or not ) CFSwapInt16BigToHost() in appropriate locations. BTW: just to double check, are you describing an application crash or an FBtoC crash? The subject says "FBtoC crash" but I assume that means "application crash when compiled with FBtoC", right ? The comment in your first post on the topic was also confusing to me ( repeated above , so I want to make sure we know the basics. Brian S.
