Issue: dev-embedded/xa-2.3.14 leaves trace of segfault in dmesg.
Discovered on: amd64 (internal ref: ci)

NOTE:
To reproduce this issue:
1) Install the package with FEATURES=test
2) Check dmesg output with: dmesg -T | grep -E '( segfault | traps:| audit:)'

This type of report comes from a check that is a bit outside of the tinderbox, that's the reason because build.log was not provided (however in cases like these the build.log doesn't help much) but if you need further help to diagnose this issue feel free to ask.

In any case I'm providing what I can see via dmesg.

Test suite has several expected failures like:

# xa should not allow this to happen. if it does, this test is no good.
../../xa -DBUG=1 -o test.o test.s || exit 0 && exit 1
 .data
test.s:line 6: 1000:Illegal segment error
Break after 1 errors

So I think this is normal, or either way it's not ignoring errors so I don't think there's anything to fix here (just test suite noise).

(well, it does feel kind of questionable still but well)
