#3967: Adding heap profiling RTS options causes segfault
-------------------------------+--------------------------------------------
Reporter: tibbe | Owner:
Type: bug | Status: new
Priority: normal | Component: Profiling
Version: 6.13 | Keywords:
Os: Linux | Testcase:
Architecture: x86_64 (amd64) | Failure: Runtime crash
-------------------------------+--------------------------------------------
Adding either `-hy` or `-hc` causes a segfault in the `thread-delay`
benchmark. To reproduce:
{{{
git clone git://github.com/tibbe/event.git
cd event
autoreconf
cabal configure --enable-library-profiling
cabal build
$EDITOR benchmarks/Makefile
}}}
Change the last line in the following section:
{{{
thread-delay: ghc-flags += -package stm
thread-delay: $(lib) Args.o ThreadDelay.o
ranlib $(lib)
$(ghc) $(ghc-flags) -threaded -o $@ $(filter %.o,$^) $(lib)
}}}
to
{{{
$(ghc) $(ghc-flags) -threaded -rtsopts -o $@ $(filter %.o,$^)
$(lib)
}}}
This enables the +RTS options. Finally, run:
{{{
make -C benchmarks/ clean thread-delay ENABLE_PROFILING=1
./benchmarks/thread-delay -n50000 +RTS -hy
}}}
This gives me a segfault.
