The patch provided by Andrey Zonov helps, segfaults disappear. Looks like the asm version of the longest_match() function has some bug or architecture incompatibility. The error happens not regularly, probably in very special case. We got it using PyQt to paint jam tiles basing on our data, only sometimes - after 5-30 minutes of intensive continuous painting, independently on using multi-thread features. The (pseudo)stack was always looking like: longest_match() deflate_slow() deflate() --- libpng functions --- --- Qt functions --- --- PyQt functions --- --- Python interpreter --- Regards, Vsevolod Novikov _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
