--- Comment #11 from Nick <nickpapior at gmail dot com> --- Created attachment 38492 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=38492&action=edit make check output I recompiled gcc on the Opteron6136 machine. I ran the test-suite: make -k check > test.out Doing: grep -e FAIL -e ERROR test.out only returns two lines. Those lines only appear due to "WERROR=" lines. I also tried: gcc -O2 -march=opteron -c zunhj.f to no avail. All-in-all, the bug persists. :( I have attached the gz of the make check.
