It's doing a fetch of a remote http server...
I hit this once. Then ran the gdb and hit it again.
I installed libcurl3-dbg and was unable to get it to reproduce again after that.
(gdb) set args fetch ds
(gdb) go
Undefined command: "go". Try "help".
(gdb) run
Starting program: /usr/local/bin/git fetch ds
