#3215: Calling freeHaskellFunPtr on the current function
-------------------+--------------------------------------------------------
Reporter: cmcq | Owner:
Type: bug | Status: new
Priority: normal | Component: Runtime System
Version: 6.10.3 | Severity: normal
Keywords: | Testcase:
Os: Linux | Architecture: x86
-------------------+--------------------------------------------------------
This is based on code in gtk2hs.
$ valgrind -q ./finalizer_queue
finalizer_queue: internal error: stg_ap_v_ret
(GHC version 6.10.3 for i386_unknown_linux)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
Killed
Unfortunately this test doesn't crash without Valgrind.
My guess is that this bit is the problem:
finalizer <- fixIO $ \dPtr -> mkThunk $ do
freeHaskellFunPtr callback
freeHaskellFunPtr dPtr
Perhaps the documentation should say not to do this?
