severity 350088 grave
reassign 350088 libmhash2 0.9.4a-1
retitle 350088 libmhash2: crc32 segfaults on big endian machines
tags 350088 + patch
thanks
Hi,
this is a bug in the new libmhash2 version 0.9.4a. The severity is grave
since it breaks existing software using the library (in this case
gringotts).
Uwe, if you want you can recompile libmhash2 with the attached patch and
see if it works. I cannot test this since the bug only occurs on big
endian machines like your powerpc.
Kind regards,
Bastian
