This results in an invalid free() & segfault because you're freeing
&lines which may not have been allocated by string_list_init().
Good point. Did my tests not catch this? (seems it requires calling
`git commit-graph write` with no `--stdin-packs` or
`--stdin-commits`).
Most of your tests (t5318-commit-graph.sh) segfaulted, but presumably
you're on a more forgiving compiler/platform/options. I compiled with
-O0 -g on clang 4.0.1-8 + Debian testing.
I appreciate the extra platform testing. I'm using GCC on Ubuntu (gcc
(Ubuntu 7.3.0-16ubuntu3) 7.3.0).
While the errors didn't repro on my box, they did on the VSTS Linux
build machines [1]. I created an internal PR just so I could run those
tests (and on our OSX agents which use clang) and so I can verify I
fixed the situation. I'll send a v6 soon so Junio only picks up a
version that succeeds in tests.
Thanks,
