Comment:
I'm really NOT understand this crash.
On frame #2, gnulib's `canonicalize_file_name` was called, which in turn call `__realpath`, which `malloc` some 4096 bytes, but some how `free`-d afterward, without any trace of `free`. I'll see if patching `canonicalize_file_name` to use musl's `realpath` works?
