--- Comment #5 from Elmar Stellnberger <estellnb at elstel dot org> --- Created attachment 52827 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52827&action=edit 2nd version of patch that should be useable under gcc-8-8.3.0/debian/patches/ Last time I reported that I could not test the patch posted here because the result of package creation with dpkg-buildpackage had vanished. Luckily I found gcc/xg++ and gcc/xgcc which were the required executables that could be installed into /bin/ and tested whether they compiled the new Firefox. g++ with the last patch did not do this. Consequently I have checked out 10.2.2, newer than the last known working good one (10.1.1) from Debian 11 and analysed all changes along the backtrace again. What I found is condensed in the patch above: discover_nonconstant_array_refs (); - was moved up in addition to the other change tested already before If the error is evoked by what is called along the backtrace this needs to resolve it. (I assume now that the Qt5/moc bug is independent and do not use it as reference for the gcc version to compare against any more). Otherwise, the error may stem from something done in a previous pass: during RTL pass: expand Unfortunately this time I was not even able to compile gcc/xg++. Makefiles were garbled, xgcc did not produce a.out (test in Makefile), texinfo files were invalid and I had to copy them from a fresh root and ultimately xg++ stayed the same after all. I had rescued the original g++ as /bin/g++ and that one turned into a link (I know it was a regular file before) although all debian/rules Makefiles only ship into debian/tmp/usr/... and not /. Absolutely no chance to test this second patch! Perhaps someone else can do.
