I realize that the answer to my question was in the subject of your bug report. You said you built these on an amd64 system. That's the same architecture as my system. I think I was able to reproduce the bug. First, like you suggested, I built Guix using commit f47e761a10675b05b07107035d5024618267a3ad (from your repo). Then I ran: guix build --target=powerpc64-linux-gnu bootstrap-tarballs I found guile-static-stripped-2.2.6-powerpc64-linux-gnu.tar.xz in the output of that build. I extracted it and used qemu-ppc64 to run it, which produced a segfault: --8<---------------cut here---------------start------------->8--- $ /gnu/store/dilkq36pawdqh050gd09d1incskpqjj7-qemu-5.0.0/bin/qemu-ppc64 bin/guile guile: warning: failed to install locale Segmentation fault (core dumped) --8<---------------cut here---------------end--------------->8--- I wonder if this is the same segfault you're seeing? I had to use QEMU because I don't have a powerpc64 system. Maybe this will enable me to debug further, even though I don't have any powerpc64 hardware. I will keep investigating. -- Chris
