If you're like me and going crazy at the lack of usable Rust stack
traces in Mac OS X, I prepared a binary patch to the system GDB. Steps
1. Download the patch and save to apple-gdb.bsdiff
2. $ brew install bsdiff
3. $ bspatch /usr/libexec/gdb/gdb-i386-apple-darwin my-gdb apple-gdb.bsdiff
4. Follow the instructions here to create a custom code signing cert:
http://sourceware.org/gdb/wiki/BuildingOnDarwin 5. $ codesign -f -s gdb-cert my-gdb
Then use my-gdb to debug Rust, and enjoy your stack traces!
