Just a note: reproducible on s390/zelenka.d.o with

 perl -Iblib/lib -Iblib/arch -MData::Alias -e '{alias local $x}'

Core was generated by `perl -Iblib/lib -Iblib/arch -MData::Alias -e {alias local $x}'.
Program terminated with signal 11, Segmentation fault.

I suppose Data::Alias is corrupting the stack somehow.

FWIW, the list of architectures looks like all our big-endian ones.
