dialog_pickfile with multiple_files crashing IDL [message #35098]

Hi,

I'm running IDL 5.6 on Solaris 8.

I want the user to be able to select multiple files using the
dialog_pickfile widget with the /multiple_files flag. This
works fine for the most part, but if I select many files
(say over 1000 files), instead of returning the expected list,
my entire IDL session crashes after the following message:

IDL> Error: Cannot perform malloc

Has anyone seen this before? Is there a workaround?

The largest number of files I was successfully able to select was
587 - though at that point, I wasn't increasing the number one by
one. The limit is probably determined by the length in
characters of all files (including full path names) selected.

Still, in terms of memory, this is a piddling amount. Why is
my IDL session crashing?

Thanks for any info.

-Jonathan
