--- Comment #9 from Bill Seurer <seurer at linux dot vnet.ibm.com> --- Systems where I see it fail: granola yavin3 Systems where I do not: bns All are power7 BE systems. I didn't do anything special on any of the systems. I ran configure like this on all of them: /home/seurer/gcc/gcc-test/configure --prefix=/home/seurer/gcc/install/gcc-test --enable-languages=c,fortran,c++ --disable-multilib --disable-libsanitizer --disable-bootstrap Different compiler versions were used to build on all of the systems. seurer@bns:~/gcc/build/gcc-test$ $CC --version gcc (SUSE Linux) 4.3.4 [gcc-4_3-branch revision 152973] On bns I also tried a bootstrapped gcc 7.0 and the test case still worked there. seurer@yavin3:~/gcc/build/gcc-test$ $CC --version gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-16) seurer@granola:~/gcc/build/gcc-test$ $CC --version gcc (GCC) 5.3.0
