This seems very specific but I did happen upon it organically. What were the chances? lol
Also adds a regression test, which causes previous chibicc version to deref NULL and segfault (the cc1 process dies with SIGSEGV, which causes the driver to
exit(1)
).I think I'm right to assume that the only way
mem->name
can be NULL is ifmem
is an anonymous union/struct? Just wanted to make sure
