shared library bus error on OS X

[igloo]

The #3807 test T3807 is giving "Bus error" on OS X.

I've had a very quick prod with gdb, but some odd things seemed to be happening.

Is this "Bus error" related to the SIGBUS of ticket #3654 ?

[altaic]

Could this ticket be related to ticket 4804 which I filed a few days ago? I am attempting to diagnose that ticket, but unfortunately "Bus Error" doesn't really point me in a direction. I seem to recall some tickets relating to mach-o relocation tables and bus errors, though so maybe I'll start there.

Is that on a 32-bit or 64-bit? On OS X 10.7 (Lion) with in a 64-bit build, I get

=====> T3807(normal) 587 of 2970 [0, 0, 0]
cd ./dynlibs && $MAKE --no-print-directory -s T3807    </dev/null >T3807.run.stdout 2>T3807.run.stderr
cd ./driver/T3007 && $MAKE -s clean
Wrong exit code (expected 0 , actual 2 )
Stdout:

Stderr:

T3807Export.hs:1:1:

    Perhaps you haven't installed the "dyn" libraries for package `base'?
    Use -v to see a list of the files searched for.
make[3]: *** [T3807] Error 1

It was probably 32bit.

    Fix #4264 on OS X

    We were getting the RTS linked twice, which caused odd things to happen.
