#9152: internal error: scavenge_stack: weird activation record found on stack ----------------------------------+--------------------------------- Reporter: mjo | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 7.8.2 Keywords: | Operating System: Linux Architecture: x86_64 (amd64) | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------------+--------------------------------- This is a semi-reproducible error that shows up in the test suite for http://hackage.haskell.org/package/htsn-import. You have to run the test suite a few times, but it does crash regularly. Steps to reproduce: {{{ $ ghc --make -O2 -o setup Setup.hs $ ./setup configure --user --enable-tests $ ./setup build $ ./setup test testsuite }}} If that doesn't crash, `./setup test testsuite` can be re-run until it does. Sample crash: {{{ $ ./setup test testsuite Running 1 test suites... Test suite testsuite: RUNNING...
