Comment (by bmundim):

 It worked for me on linux CentOS 5. Now the backtrace didn't include the
 symbols:

 Backtrace from rank 1 pid 21481:

 I had OPTIMISE = yes in my configuration file but I also had CFLAGS = -g
 -debug all ...
 So -g doesn't seem to be passed along here. If we don't have the symbols
 then it
 becomes much harder to debug. In any case, apart from this detail, I would
 say this
 patch looks good for applying.
