Meanwhile, I have updated several other Gentoo systems (32 and 64 bit) which all worked well. It's just that one system which brings that error. I have also found https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79827 and made "ulimit -s 32768" (instead of 8192), but to no avail. The only difference is the kernel (4.0.5 on the old system; all others have 4.14.83 oder even some 5.x kernel). On the other hand: the difference between gcc 11.2.1 (which works fine) and 11.3.0 shouldn't be that big?! -Matt
