#15544: Non-deterministic segmentation fault in cryptohash-sha256 testsuite -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): I can't reproduce any failures in this program without using debug runtime and enabling sanity checks with `-debug -rtsopts -with-rtsopts=-DS` (tried with `--timeout 1s` too). When I enable sanity checks I get: (this is with GHC HEAD) {{{ test-sha256: internal error: ASSERTION FAILED: file rts/sm/Sanity.c, line 851 (GHC version 8.7.20180827 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug zsh: abort (core dumped) cabal new-run --with-ghc=ghc-stage2 --enable- test --allow-newer -- -j 8 999 }}} every once in a few runs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15544#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
