COREOS_BOARD=""
Environment
SDK
Expected Behavior
Although perl isn't includede in images, it's actually built I needed it to add a custom package. The problem is that crosscompiled perl doesn't work actually. Simple test in SDK:
$ LD_PRELOAD=/usr/lib/libperl.so.5.24.1 /build/amd64-usr/usr/bin/perl -V
Summary of my perl5 (revision 5 version 24 subversion 1) configuration:
Platform:
osname=linux, osvers=4.14.11-coreos, archname=x86_64-linux
...
Actual Behavior
But the crosscompiled libperl segfaults:
$ LD_PRELOAD=/build/amd64-usr/usr/lib/libperl.so.5.24.1 /build/amd64-usr/usr/bin/perl -V
Attempt to free unreferenced scalar: SV 0x55a85b85b0e8 at /usr/lib64/perl5/5.24.1/strict.pm line 38.
Segmentation fault
Reproduction Steps
- Build a SDK and try to actually use perl with crosscompiled libperl.
Additional info
I played with some tests and find out that the problem appeared with switching to gcc6, there was no problem with older gcc version. I also tried to upgrade the dev-lang/perl to the newest 5.26.1-r1 from Gentoo and it didn't change anything – the problem remained.
