GoogleCodeExporter commented 9 years ago 
perlcc -O3 -e 'format OUT =
bar ~~
.
open(OUT, ">foo") or die;
write(OUT); close OUT;
'; ./a.out
zsh: segmentation fault  ./a.out

other optimization levels don't segfault.

format strings with ~ may not be static:

doparseform:
           case '~':
               if (*s == '~') {
                    repeat = TRUE;
                    *s = ' ';
                }
