hDuplicateTo001 crash in profthreaded way
I have observed this crash of the hDuplicateTo001
test in the validate-x86_64-linux-deb9-debug
job:
cd "libraries/base/tests/IO/hDuplicateTo001.run" && ./hDuplicateTo001 +RTS -p -RTS <
Wrong exit code for hDuplicateTo001(profthreaded)(expected 0 , actual 134 )
Stderr ( hDuplicateTo001 ):
hDuplicateTo001: internal error: Itimer: read(timerfd) failed
(GHC version 8.11.0.20191211 for x86_64_unknown_linux)
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
h: Aborted (core dumped)
My gut tells me that this is an interaction between hDuplicateTo
and itimer
(used by the profiler).
