FWIW, it looks like all of the remaining leaks are in gcc.c (the
"driver" code, for the "gcc" binary).   IIRC most of this relates to
long-standing code that was written with the assumption that it will
only be run once and not persist in memory, and so it tends to mix up
string literals and dynamically-allocated strings without bothering to
free them (the pointer values persist to the end of "main" when run
from gcc, but get cleared when run from libgccjit.so).

Patches to clean these up would be great.  That said, I'm not the
driver/gcc.c maintainer, so I can't formally approve them (but can post
+1 emails if they look good to me)  [1]

Dave
[1] also, I'm on vacation, so sorry in advance for any slow responses
to email.
