Re: [MACTCL] Problems loading .dylib files in Wish Shell using File->Source

Michael, No idea what is going on here. The "halt" that is being called here is dyld's "really bad" error function. For some reason it throws a breakpoint trap, rather than an abort or something. Anyway, what is happening is that when you register a signal handler, dyld immediately fully binds the module containing the signal handler - so that it won't have to try to bind anything when it is actually trying to handle the signal (usually not a good time to be doing lots of work). For some reason, this is failing. No idea why, though. CrashReporters backtrace looks like it got a little mangled. From looking at the source, link_in_need_modules doesn't call halt. BTW, the source for dyld is in the cctools project in the Darwin Project sources, if you want to have a look yourself. You can run this under gdb and try breaking on __dyld_halt (gdb prefixes the private dyld symbols this way so we can keep dyld symbols apart from normal symbols). This should break in gdb, and you can look up the stack to see what is going on. Maybe gdb can give you a better stack crawl.
