Bug 614372 – sys-apps/sandbox-2.10-r3 causing cc1 segmentation faults

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

[Description Jan Ziak (atomsymbol) 2017-03-31 18:53:56 UTC]

Hello

Context: I added the x32 ABI to the list ABIs and in consequence of this I recompiled many packages. The original ABIs were: amd64, x86.

In consequence of the recompilation, a few packages are now failing to build due to various reasons.

One reason for failures is a SIGSEGV in gcc's cc1. For example, here is the gdb backtrace for sys-libs/e2fsprogs-libs-1.43.3:

$ pwd
/var/tmp/portage/sys-libs/e2fsprogs-libs-1.43.3/work/e2fsprogs-libs-1.43.3-abi_x86_x32.x32/util

$ gdb /usr/libexec/gcc/x86_64-pc-linux-gnu/6.3.0/cc1 core.26826
Core was generated by `/usr/libexec/gcc/x86_64-pc-linux-gnu/6.3.0/cc1 -E -quiet -I . -I ../lib -I /var'.

What are your flags on sys-apps/sandbox? Do you have abi_x86_x32 enabled there?

The enabled flags were: ABI_X86="32 64 x32"
