Oddly, running under `strace -f` and `ltrace -f` suppresses the trap error and gives a SEGV instead.

Running under `gdb` doesn't reveal anything interesting *unless* you do `set follow-fork-mode child`.

But its not obvious to me if that is the same problem I'm seeing due to it manifesting differently.

Which version of dev-libs/libnl do you have?
Comment 2 Kent Fredric (IRC: kent\n) (RETIRED) gentoo-dev 2014-06-30 14:51:31 UTC
[IP-] [  ] dev-libs/libnl-1.1.4:1.1
[IP-] [ -] dev-libs/libnl-3.2.25_rc1:3


Huh. I see that last one is keymasked. I'm not sure how that happened, will try downgrade to ~ and see if that helps.

Yep. Indeed, this looks like a duplicate of #515132
