If I’m running from Xcode 4.6.3 on Mavericks...
daemon(0,0); // no matter the values of the args
dlopen(full path, RTLD_NOW);
gives me this:
0 dyld 0x8fe0d652 gdb_image_notifier(dyld_image_mode, unsigned int, dyld_image_info const*) + 1
1 ??? 0000000000 0 + 0
2 dyld 0x8fe046ae dyld::notifyBatchPartial(dyld_image_states, bool, char const* (*)(dyld_image_states, unsigned int, dyld_image_info const*)) + 761
3 dyld 0x8fe021d1 dyld::notifyBatch(dyld_image_states) + 23
4 dyld 0x8fe0e6d1 ImageLoader::link(ImageLoader::LinkContext const&, bool, bool, bool, ImageLoader::RPathChain const&) + 103
5 dyld 0x8fe04905 dyld::link(ImageLoader*, bool, bool, ImageLoader::RPathChain const&) + 176
6 dyld 0x8fe0c1ef dlopen + 459
7 libdyld.dylib 0x9a692b84 dlopen + 70
Switching to dlopen first fixes the problem. However the code that does the dlopen() isn’t fork safe so it really needs to come after the daemon call.
Everything is okay if I run from the command line.
It is inconvenient to not be able to run from the debugger...
Thanks for any help or links,
Jim
