Source: gcc-10
Version: 10.1.0-2
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
I'm not sure exactly what is going on here, but in gcc-10_10.1.0-2
building the Architecture: all packages on the buildds, the stage2
build seems to have failed to run ${build_directory}/build/./gcc/xgcc.
The stage1 build was fine:
https://buildd.debian.org/status/fetch.php?pkg=gcc-10&arch=all&ver=10.1.0-2&stamp=1589559884&raw=0
> /<<PKGBUILDDIR>>/build/./gcc/xgcc -B/<<PKGBUILDDIR>>/build/./gcc/ -xc
> -nostdinc /dev/null -S -o /dev/null
> -fself-test=../../src/gcc/testsuite/selftests
> cc1: note: self-tests are not enabled in this build
> echo timestamp > s-selftest-c
...

> -fself-test=../../src/gcc/testsuite/selftests
> cc1plus: note: self-tests are not enabled in this build

but then during the stage2 build, the same thing failed:

I've given this back to try to confirm whether this is a race condition
in the build system, or a reproducible regression since 10.1.0-1.
