Hi, I try to build a program but it happen internal compiler error. But if I change -O1 to -O2 the error is gone. I attach my test file and log. Is this really compiler error? http://www.nabble.com/user-files/340/test.tar.bz2 test.tar.bz2 Thanks your help. -- View this message in context: http://www.nabble.com/is-compiler-error--tf2119164.html#a5844566 Sent from the gcc - Help forum at Nabble.com.
