There are some invariants that are being violated by pthread_kill(id, SIGINT)
and I'm having difficulty understanding them. I get the following errors:
cd ./concurrent/should_run && '/home/ezyang/Dev/ghc/inplace/bin/ghc-stage2'
-fforce-recomp -dcore-lint -dcmm-lint -no-user-package-conf -rtsopts
-dno-debug-output -o foreignInterruptible foreignInterruptible.hs -threaded
-debug >foreignInterruptible.comp.stderr 2>&1
cd ./concurrent/should_run && ./foreignInterruptible </dev/null
>foreignInterruptible.run.stdout 2>foreignInterruptible.run.stderr
Wrong exit code (expected 0 , actual 134 )
Stdout:
Stderr:
foreignInterruptible: internal error: WEAK object entered!
(GHC version 6.13.20100908 for i386_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Aborted (core dumped)
*** unexpected failure for foreignInterruptible(threaded1)
Even more curiously, though, if I hand-run the command I don't get
any problems.
