But the PPC machines that I have are single-core, so this is probably naive. I presume that you use a multi-core machine of some kind? Could you supply some additional details please? Also about the source of the GHC 6.8.2 that you use? (For example, is it some binary, from !MacPorts, built from a source distribution or something else entirely?)

A program using threads (in a somewhat naive way) crashes at runtime, only
if it is linked against the -threaded RTS, only if it is given the runtime
option +RTS -N2 -RTS, and only on powerpc. The error is:
{{{
SurfaceViewer: internal error: END_TSO_QUEUE object entered!
(GHC version 6.8.2 for powerpc_apple_darwin)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
Abort trap
}}}
To reproduce:
{{{
darcs get http://www.cs.york.ac.uk/fp/darcs/CaseTables
curl -O http://www.gris.uni-
tuebingen.de/edu/areas/scivis/volren/datasets/data/lobster.raw.gz
gunzip lobster.raw.gz
cd CaseTables
ghc-6.8.2 --make -O2 -fglasgow-exts -threaded SurfaceViewer
./SurfaceViewer ../lobster.raw 301 324 56 20 1 +RTS -N2 -RTS
}}}
If you omit the -threaded linking flag, or omit the -N2 runtime flag, then
there is no crash. I could not reproduce it on x86.
The only usage of threading is in the module Gridiness, which defines a
simple read/writer protocol through a Chan.
A different runtime crash is apparent if the bottom three definitions in
Gridiness are swapped for the top three (currently commented out), which
use a single MVar for communication rather than a Chan. In that case, the
error is
{{{
SurfaceViewer: thread blocked indefinitely
}}}
The same conditions apply: must be -threaded, must have -N2, must be on
powerpc.

Comment (by thorkilnaur):
Attempting to reproduce, I run into a darcs error probably caused by:
