 ghc-6.7.20070224(25701,0xa000ed88) malloc: *** error for object 0x3807ff8:
 pointer being reallocated was not allocated
 ghc-6.7.20070224(25701,0xa000ed88) malloc: *** set a breakpoint in
 szone_error to debug
 malloc: failed on request for 10331948 bytes; message:
 ocAllocateJumpIslands}}}

 Interestingly, when I invoke it through `gdb` the breakpoint in
 `szone_error` is ineffective (although `gdb` has in the past had enough
 bugs in its breakpoint support that I wonder if it's `gdb` that's broken
 here and not some strange confusion in what `malloc` library is being
 invoked or etc.)

 I've placed the build log (including testsuite output) from this build at
 http://www.ece.cmu.edu/~allbery/ghc67-20070218.log in case there's
 something obvious there about something I'm doing wrong.
