Description caolanm 2010-09-08 13:38:52 UTC
idlc breaks for me sometimes fairly randomly, looking closer idlc isn't getting
the expected output from idlcpp, and looking at that with valgrind shows that
its uses memcpy with overlapping areas, which causes randomlike behaviour.
Should use memmove if they overlap.

cmc->rene: as an aside, this might be the reason idlc failed on hppa sometimes
as well.

camc: thanks for the cc, but apparently it's not the case for the hppa hang.
