Hello GHC hackers,
I have been trying the recent 7.4.1-rc1 release on my OSX Snow Leopard machine. I am using the 64bit OSX .tar.bz. I used virthualenv/hsenv to set up a virtual environment to test packages with the RC, but I discovered that GHCi seems to segfault somewhat randomly when invoked.
I get this too, with the ghci-7.4.0.20111219 from GHC-7.4.0.20111219-x86_64.pkg on OS 10.6.8, and it happens about half of the time. It seems random when it segfaults and when it runs. I don't know if it's worth anything, but the gdb backtrace looks similar: (gdb) bt #0 0x00000001f6c930da in evacuate1 () #1 0x00000001f6c98868 in scavenge_block1 () Previous frame inner to this frame (gdb could not unwind past this frame) It's easy for me to repro at the moment, since I get it so frequently. I compiled a bunch of cabal packages just fine, so it seems to just be ghci and runghc.
