Subject: Segmentation fault on FreeBSD when no common substrings
I get the following error on FreeBSD 5.2.1 with Ediff 0.03 bash-2.05b$ perl -MString::Ediff -e 'print String::Ediff::ediff("Aldersgate", "Bassishaw");' Segmentation fault (core dumped) The bug happens only when the two strings have no common substring. I've tracked it down to a malloc which can allocate 0 bytes if there is no diff. Under FreeBSD this always returns 2048, which you can't write to. So when it writes a NULL in the first byte it crashes. A patch is attached
