I have read the documentation, but I could not find any reference to a
maximum image size supported. The problem does indeed seem to be memory
running out. When I increased the memory available to PHP to 50mb, the
large images no longer terminated the script.
I've changed the bug report to a 'performance problem', as I believe
imagecreatetruecolor is somewhat wasteful with resources. The script
terminates with a 1310x4000 image, about 5.3mpix in size, with a 25mb
memory limit. Apparently imagecreatetruecolor takes almost twice the
memory it should.
Sorry about not investigating the memory thing sooner, before
submitting. I should've thought of that myself.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
PHP crashes (probably just exists) due to reaching the memory limit and
being unable to allocate additional memory.
