[Tinycc-devel] Seg fault with test 114 on Debian x64

[Christian Jullien]

Hi again Herman,

I continue to test mod with your latest patch on the (many) machines I have.

This time, it is a Debian 10.6 x86_64 fully up to date and, guess what?, it fails on test  114 with clang 7.0, (gcc worked).

See log below:
