hDuplicateTo001 crash in profthreaded way
I have observed this crash of the
hDuplicateTo001 test in the
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 18.104.22.16891211 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
itimer (used by the profiler).
