Hi,

If nodejs 18.6.0 is built using gcc-12, several tests fail,
but not when built using gcc-11 (all other things being equal).

*Only* on mips64el and riscv64.

In the logs, some new warnings show up, maybe that can help:
https://buildd.debian.org/status/fetch.php?pkg=nodejs&arch=mips64el&ver=18.6.0%2Bdfsg-4&stamp=1659454899&raw=0

in particular:
/usr/include/c++/12/bits/atomic_base.h:488:31: warning: ‘long unsigned int 
__atomic_load_8(const volatile void*, int)’ writing 8 bytes into a region of 
size 0 overflows the destination [-Wstringop-overflow=]
  488 |         return __atomic_load_n(&_M_i, int(__m));
