--- Comment #6 from Arseny Solokha <asolokha at gmx dot com> --- There must be something wrong w/ the way I configure gcc, then. It takes indefinite time compiling the testcase only at -O2 or -Os and finishes instantly at any other optimization level. But it also finishes instantly when I add -fstack-protector or -fno-stack-protector - strangely, either of them. What additional info should I provide? config.status, maybe?
