Hi, I'm currently working on updating the GHC port to 6.6.1 for OpenBSD, and when I run the testsuite (ghc-regress), all test cases for the way "threaded1", i.e. debug + threaded bail out with an assertion failure: Blocks: 132 live + 123 free = 255 total (508 around) conc010: internal error: ASSERTION FAILED: file Storage.c, line 1174 The numbers vary slightly, but there's always a total of 255 and 508 blocks around, except for one test case (con012), where there are a total of 763 blocks (1016 around). What puzzles me a little bit is the fact that this does *not* happen on amd64 (aka x86_64) but only on i386 so far. So does this ring a bell for anyone? I didn't find anything similar in the archives or in the bug tracker. Ciao, Kili -- CRM114 isn't ugly like PERL. It's a whole different kind of ugly. -- John Bowker
