The error is known and does not appear in the same version of amd64 Debia= n. It does not appear with newer versions like Debian11/Bullseye/g++ 4:10.2.1-1 I get another type of error with Qt5/moc (meta object compiler for genera= ting signal handler procedure signatures): usr/include/c++/8/bits/stl_relops.:67: Parse error at "std" /usr/include/c++/8/bits/stl_relops.h start like any .h in bits/ and shoul= d be correct. Like the internal compiler error from above this one appears only = in i586, but with a wide variety of distributions: i586 Debian10 gcc 8.3.0-1: bad (likewise bad Ubuntu19.04) i586 Ubuntu19.10 gcc 9.2.1: good I will appreciate any hint to what the bug could have been related to. I would like to develop a patch to fix things for Debian10/i386 but do not re= ally know on where to start looking for. I could neither find init-first.c nor libc-start.c looking for such files in the source directory gcc-8-8.3.0.=
