[Tinycc-devel] TCC segfault on Fedora 30

[Klaus Ebbe Grue]

Hello,

Just a short note: my tcc did segfault on Fedora 30.

Workaround: git clone git://repo.or.cz/tinycc.git, recompile, reinstall

Is that something one should do for each new Fedora?

Cheers,
Klaus

# So:
# tcc segfaults when trying to compile hello.c (identical to examples/ex1.c).
# But when invoked without parameters, tcc responds with the help text.
