Bug ID: 70789
Summary: cilk test fib-tplt.cc occasionally fails
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bernds at gcc dot gnu.org
Target Milestone: ---
Target: x86_64-pc-linux-gnu
I've had a test run fail with
FAIL: g++.dg/cilk-plus/CK/fib-tplt.cc -g -fcilkplus execution test
This was while testing the -m32 variant. I've let the test run in a loop for a
few hours, and it seems to fail sporadically with a segfault, almost certainly
not because of the fairly harmless patch I was testing. I've tried to load the
coredump into gdb, unfortunately it's not very informative.
(gdb) bt
#0 0x00001c46 in ?? ()
#1 0xf76d3587 in ?? ()
#2 0xf76d3347 in ?? ()
#3 0x00000000 in ?? ()
Tagging it as wrong-code although I'm not sure whether the testcase is valid.
We seem not to have a libcilkrts component.
