</span>Perhaps <a href="http://gcc.gnu.org/PR60871" target="_blank">http://gcc.gnu.org/PR60871</a> , but without a preprocessed testcase it<br>
is hard to tell.<br>
You could either try local mock, or you could hack for a temporary build<br>
small *.spec file change that would BuildRequire: sharutils<br>
and run:<br>
make ... || tar cjf - /tmp/cc*.out | uuencode cc.tar.bz2<br>
(that way you could download build.log and uudecode the tarball with the<br>
preprocessed source from it).<br>
<br>
As a workaround, supposedly -fno-devirtualize or<br>
-fno-devirtualize-speculatively options could help.
