internal error: END_TSO_QUEUE object entered!

(GHC version 6.8.2 for sparc_sun_solaris2)

This error occurs if I pass -optc-O2 or greater. At -optc-O1 it does not occur.

Thanks for the report; however, without a test case this is virtually impossible to fix, or to confirm that we have fixed the bug that you are seeing. Can you please attach some code that triggers the problem to this ticket, and say exactly what commands you are running?

I've attached a tarball of my project source. I'd narrow it down if I knew how to with haskell tools. make in the project directory should build the executable Solve.

Run: ./Solve bf irv u-3-15

Changing -optc-O3 to -optc-O1 in the Makefile causes the bug not to occur.

Let me know if I can assist in simplifying the code.

Can you send the output of ghc --info please?

If it's a registerised compiler then we don't support changing the optimisations that gcc does, as the assembly mangling we do may get confused.

On the other hand, if it's unregisterised then it points to a bug either in gcc or the code that we generate.

  • Resolution set to invalid
  • Status changed from new to closed

OK, so that says that it's not unregisterised, and therefore using -optc-O3 isn't supported. If you stick with passing just -O of -O2 to GHC then it should work.
