hi!

Thanks for your bug report.  Unfortunately, I can't reproduce it here: pinfo simply says "B??dne wyra?enie regularne; Naci?nij dowolny klawisz" and doesn't segfault.

If you're familiar with a debugger, could you check if pinfo_re_comp() in utils.c does indeed return -1 as it should if you enter an invalid regexp?

Thanks,
Bas.
