Segmentation fault with CDF routines under Linux

[riglerej(at)my-deja.com]

Using both 5.3, and 5.4, I consistently have problems with seg-faults
when trying to run various CDF routines under Linux.  I'm fairly new to
using IDL to read CDFs, but I'm not trying to do anything strange.  In
fact, I can't even get cdf_open to work.

Specifically, I have a problem when my argument to cdf_open is a string
provided by the findfile routine.  If I type in my own string,
everything works great, but if it comes from findfile, I get a
seg-fault.  The exerpt below is copied exactly from my session, an
should give a very clear idea of what is happening...

Can anyone else recreate this on Linux, or with versions other than 5.3
and 5.4?  I tried this with several different cdf files, so I don't
think it is a problem with the file format.  Any other ideas?

P.S. While I'd love to move to HDF, that is not an option, so it might
be wisest not to make that suggestion.
