Bug ID: 102742
Summary: ERROR: descriptor 3 still open after tests complete
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libbacktrace
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: ian at gcc dot gnu.org
Target Milestone: ---
>From time to time, I see this failure when I run tests when I run e.g.
make -j16 check -k RUNTESTFLAGS="dg.exp=pr64637.c"
ERROR: descriptor 3 still open after tests complete
ERROR: descriptor 4 still open after tests complete
However, running with -j1 it's gone. I'm pretty sure these FDs belong to
jobserver and I can prove it with:
diff --git a/libbacktrace/btest.c b/libbacktrace/btest.c
index 9f9c03babf3..f9be9a26db4 100644
--- a/libbacktrace/btest.c

state = backtrace_create_state (argv[0], BACKTRACE_SUPPORTS_THREADS,

Then I see:
XXX: kw -j16 --jobserver-auth=3,4
in test-suite.log.
