--- Comment #3 from Elmar Stellnberger <estellnb at elstel dot org> --- Created attachment 52823 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52823&action=edit patch that should be useable under gcc-8-8.3.0/debian/patches/ I have recompiled g++ and the output of dpkg-buildpackage -b -kestel...@elstel.org -nc tells me that it should have successfully created the respective .deb package files as before. I have looked into the same directory as before but unfortunately I found not a single .deb there and nowhere else under /usr/src. The files can only have been deleted like the ssh user from /etc/passwd at my nslu2 machine. Another time I found out about a chmod -x /etc/init.d/sshd as I suddenly could not connect to my nslu2 via ssh any more. This looks very similar as what I have experienced with arm-linux-gnueabihf-ld when the program did neither produce an error message, an !=0 return value and no output file as given with -o txtfmt. This was when I had all options right to what I can assess, i.e. just before it must have worked. As for now I can not find out whether the patch really resolves the bug. Someone else will have to be as nice to recompile for me. The patch makes a forward change to a known good g++ (version as suggested by use of moc/Qt5 rather than by building Firefox however). It patches the only piece of code that was different along the backtrace of Firefox-esr-91.8.0esr.
