This bug affects 4.5.0. I can not say for certain about earlier versions. Due to the inevitable Stage 2 -O2 failure in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40513, the lines are blurred a bit looking backwards.
Very similar to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40513 I have just reported. The bug's result is a very simple: $ ./gcc /home/Peter/test.c gcc.exe: CreateProcess: No such file or directory $ ./gcc /home/Peter/test.c -o test.o gcc.exe: CreateProcess: No such file or directory I have successfully cross-compiled a build using Ubuntu Linux that is unaffected, using the same libraries. The problem affects all the other drivers as well.
