'convert' PSD->PDF OOM on Mac OS X 10.6.3

[darkart]

'convert' fails to convert some PSD files to PDF on Mac OS X 10.6.3 as it tries to allocate a very very large chunk of memory (18+ quintillion bytes, but not all bits in a 64bit integer are turned on). It reports that the error is:

@ error/pdf.c/WritePDFImage/1557

This is ImageMagick 6.6.2-0 built 64 bit on Mac OS X 10.6.3. Unfortunately I can't post any of the files that show this problem, but I can do further digging into the files if anyone has ideas on what might be going on.

TIA

We have a few patches in ImageMagick 6.6.2-2 Beta to improve PSD support. We could use help, the PSD image format is complex.

We may be able to help test, unknown if we can help with coding due to limited resources but pointers to things to check on would help in that area.

I forgot to mention that these files have been fine with Mac OS X 10.5.8 and 32bit 'convert', have not tried building ImageMagick 32bit on 10.6.3 to see if that still works.

FYI-
This problem appears to be fixed in 6.6.2-9. Data that exhibited the failure now works properly. Thanks much!
