runtime: TestGdbPython flaky on linux/arm64 and linux/s390x builders #15599
The TestGdbPython test sometimes fails with:
GOMAXPROCS=2 runtime -cpu=1,2,4
--- FAIL: TestGdbPython (0.37s)
This last happened with commit 6662897 on June 9th. A few commits later was cbc2686, which fixed a bug with GDB backtraces. There haven't been enough commits since 6662897 to be statistically sure that this is fixed, but I suspect it is.
CL 23481 did capture a stack at the failure:
This is also right where cbc2686 changed things.
I'm trying to reproduce this using gomote to confirm the fix, but not having any luck.
Reproduced once out of ~100 runs at 6662897 on the linux-arm64-buildlet by running
I'm going to run cbc2686 over night and see if it still reproduces.
