hey there, 

I really hope I'm not misstaken here - tried to cross compile spidermonkey-91
from an amd64 host to an armv7a target to me it seems that there is possibly a
bug somehwere in libstdc++-v3?

I will attach the full and compressed build log

toolchain is: 

gcc-12.1.0, binutils-2.37_p1-r2, glibc-2.34-r13 and rust 1.59.0; on a
gentoo-amd64 machine
