I vaguely remember seeing something like this on my old G5 once...I think it was the random number generator? Or some related to Solomon's approximate priority queue...

Never tried it on a G5 before. It looks like it's trying to create an array of somethings that need to be aligned, but they don't have a size that makes sense for alignment (i.e. a 15 byte sized object). I'm not sure why the size of the object isn't a multiple of the Alignment, since it is on other systems.

Is it possible to run this in the debugger and get a stack trace. We need to know which object isn't the right size and what the size of the object is.

Thanks,
James

Hello everyone-

When I run manta with the deadline image traverser on my G5 (holden.sci.utah.edu) this is what happens:

roni@holden:build$ bin/manta -imagetraverser deadline
manta.cc (top level): Caught SCIRun exception: An InternalError exception was thrown (Attempting to allocate an array of objects that cannot be aligned. Please make sizeof(ParentT) a multiple of Alignment).
/home/scinew/roni/research/Manta/Core/Util/AlignedAllocator.h:64

That happens for REAL=double and REAL=float.
