Any chance a cooling fan inside died and you are overheating it? Can you reproduce the failure with other heavy load programs, can you run a widget that monitors the internal temperatures and other sensors during the build? It does seem odd...

Are you building inside a Parallels VM?  If so, it is probably a Parallels bug (which also explain why compiling GHC can lead to a kernel panic).

If the GHC build is not in a Parallels VM, I would suggest to shut down Parallels and try again.  If the problem does not occur without Parallels running, it's probably a bug in some of Parallel's virtualisation infrastructure.

I'm not running in a VM. I shut down parallels and also unloaded its kernel extensions by running:

sudo launchctl stop com.parallels.vm.prl_naptd sudo launchctl stop com.parallels.desktop.launchdaemon sudo kextunload -b com.parallels.kext.prl_hypervisor sudo kextunload -b com.parallels.kext.prl_hid_hook sudo kextunload -b com.parallels.kext.prl_usb_connect sudo kextunload -b com.parallels.kext.prl_netbridge sudo kextunload -b com.parallels.kext.prl_vnic

It still panics. Here's the crash log without the parallels extensions:

If it also happens without Parallels running, the suggestion to check your RAM sounds like good advice.

The (OS X modified version of) memtest86 reports no problems.
