            Bug ID: 78893
           Summary: gcc-6.3.0 build fails on genattrtab on CentOS 7
           Product: gcc
           Version: 6.3.0
            Status: UNCONFIRMED

build log

I built gcc-6.3.0 on CentOS 4, 5, and 6 using the same procedures that had
worked for previous gcc-6 releases, but on CentOS 7, the build fails in
genattrtab.  genattrtab crashes pretty hard -- running it under valgrind ends
with 'Killed', and valgrind exists without giving a traceback or diagnostics.
gdb couldn't get a stack trace either. I also tried running the build with -O0.
Is there anything else that I can try? I attached a log of the configure and
make.
The system is CentOS 7.3.1611 with kernel 3.10.0-327.36.2.el7.x86_64 and gcc
4.8.5 20150623 (Red Hat 4.8.5-11).
Regards,
William
