Since this is in /usr/local/bin/, there are two possibilities: 1) you built and installed it yourself (but then it would be more likely in your $HOME/bin), or 2) you installed it via HomeBrew. I guess it is the latter. In both cases, however, you have XCode installed, so you can dig further. Yay. The thing I would do in your case would be to clone Git: git clone https://github.com/git/git then check out v2.13.0: git checkout v2.13.0 then edit the Makefile to remove the -O2 from the CFLAGS (the next step is to use the GNU debugger, and in my hands the -O2 optimization made that pretty useless), and then build with make After that, you should be able to start the command in your local GNU debugger: gdb -args ./git config --local --get user.name You will then want to set a breakpoint on the die_builtin() function: b die_builtin Now run it with the `r` command, and it should stop in the die_builtin routine, in which case a backtrace would be most helpful to figure out what is going wrong: bt If the output is not enlightening on its own, it would be nice to paste it into a reply to this mail so that the entire Git developer community can have a look.
