That bug is fixed, but it doesn't mean that no other tree-vrp bugs left. > Is it a good idea of adding -fno-tree-vrp to CFLAGS in /etc/make.conf to avoid this optimization bug for all compilation? (BTW, I leave -O3 of CFLAGS as is in make.conf and just added -fno-tree-vrp to the end of the line.) It is good idea to extract minimal bug code sample and submit it to gcc bugzilla. -- http://ache.pp.ru/Received on Sun Aug 19 2007 - 07:54:11 UTC
