Bug#980204: gdc: Resulting executables segfault on mipsel architecture (signal 11)

[Matija Nalis <mnalis-debianbug@voyager.hr>]

Package: gdc
Version: 4:10.2.1-1
Severity: normal
X-Debbugs-Cc: mnalis-debianbug@voyager.hr

Dear Maintainer,

compiling D programs with gdc produces excutable, but trying to run that executable segfaults.
I've tried various gdc flags, but never managed to produce even the simplest working program.

on Debian Sid in chroot:

(mipsel-chroot)$ printf 'import std.stdio;\nvoid main()  { writeln("Hello, World!"); }\n' > hello.d ; gdc  hello.d && ./a.out
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault

This is with host running Buster with qemu-user 1:5.2+dfsg-3~bpo10+1
but the other not-too-complicated D programs fail on Debian buildd infrastructure too:
