cpfind: OSX malloc failing

[Kurt Hillig]

Running simple stitching of cylindrical panoramas, starting with 16-bit TIF files, typically 125-150 MB each, created by Photoshop from RAW files. I've encountered this with 2010.4, 2010.5 and 2011.0b2.

Most of the time things work very well, but for some sets I see errors like this when trying to generate control points:

 cpfind(16389,0xb030b000) malloc: *** mmap(size=63082496) failed (error code=12)
 *** error: can't allocate region
 *** set a breakpoint in malloc_error_break to debug
 cpfind(16389,0xb0513000) malloc: *** mmap(size=63082496) failed (error code=12)
 *** error: can't allocate region
 *** set a breakpoint in malloc_error_break to debug
 cpfind(16389,0xb0595000) malloc: *** mmap(size=126160896) failed (error code=12)
 *** error: can't allocate region
 *** set a breakpoint in malloc_error_break to debug

These are reproducible; they seem to happen most often with large sets (10+ files) but sometimes large ones work fine.

I'm not going to attach the most recent data set I've encountered this with - 12 files, about 1.8 GB total - but I'd be happy to provide then for whomever is willing to look into this...
