out of memory error

You have 2-3 GB memory limit [per proc] in 32bit mode.

If you really need more than 3GB of memory for this app, you can move
to a 64bit OS/machine with sufficient memory. [you can do 64bit
compiles on OSX 10.4-ppc and perhaps 10.5-intel]

Aron,

100 MB is the request for current malloc - that failed. [Previous
mallocs might have already allocated close to 2-3GB memory]
