>Description:
Every executable compiled using tcc segfaults. Interestingly,
if the "-run" is used, the program executes as expected. See
the "how to repeat the problem" below.

I tried tcc version 0.9.24 (via pkg_add) and 0.9.25 (via ports,
using gcc 4.2.1) with the same results.

This seems to be FreeBSD specific since I cannot reproduce this
on Linux (Arch, with gcc 4.4.1) at all.


>How-To-Repeat:
echo 'main(){puts("hello");}' | tcc -o output - && ./output
Segmentation fault (core dumped)

And with "-run":
echo 'main(){puts("hello");}' | tcc -run -
hello
