Created attachment 1407297 [details] bz1554030.ii Attaching the preprocessed source I'm moving this to DTS 8.1: this problem seems to be unfixable for RHEL 7. The workaround for RHEL 7 is to compile the TU with -O. This problem is fixed in DTS 8: $ g++ --version g++ (GCC) 8.2.1 20180905 (Red Hat 8.2.1-3) $ g++ -c x.ii -O2 # no crash Since it's been fixed, dev_ack+ for inclusion in DTS 8.1. Reproduced with RHEL gcc on powerpc, DTS gcc works. VERIFIED for devtoolset-8-gcc-8.3.1-3.el7. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below.
