#2563: With -N4: "internal error: RELEASE_LOCK: I do not own this lock: Task.c
269"
-------------------------------+--------------------------------------------
Reporter: TomMD | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.8.2 | Severity: normal
Keywords: | Testcase:
Architecture: x86_64 (amd64) | Os: Linux
-------------------------------+--------------------------------------------
The program crashes in various ways including double free (typical) and
sigsegv (once when -N3). The error in the subject was seen once (gdb
output attached for that run).
compile: ghc -threaded -debug ex.hs --make -O2 -o ex
run: ./ex.hs +RTS -NX -RTS file1 file2 file3 file4
where X >= 3.
It might take 4 or 5 runs to crash.
For -N4 it typically complains about a double free error, but I saw the
nicer error message once.
