AtomicPrimOps.hs flakes out for: fetchAndTest fetchNandTest fetchOrTest fetchXorTest casTest but not for fetchAddSubTest and readWriteTest. If I step through it, the segfault comes at line 166, it doesn't reach the .fetchXXXIntArray function that was called from the thread (at least ghci doesn't hit a breakpoint set at it). GDB says the bad instruction is: 4475: f0 8b 4c 24 40 lock mov 0x40(%esp),%ecx Niklas 2014-07-22 6:53 GMT+02:00 Páli Gábor János <pali.gabor@gmail.com>:

Great. Thanks all for your help!
I am afraid we are not done with this yet. Yesterday I have also committed the fix for the FreeBSD platform, but today I noticed that the corresponding test case ("AtomicPrimops") is failing due to SIGILL, that is, illegal instruction. And it has been happening for all the 32-bit platforms, including Linux [1], SmartOS [2], and Solaris [3].
I do not know yet why it goes wrong.
