INTRODUCTION:
I have recently upgraded to IDL 5.6. I have searched the web and this
newsgroup (thanks to google) for an answer and have yet to find
anything. I have used IDL for ~8 years and have never run across this
problem until now and it happens so frequently to me, I am surprised
that it doesn't affect others.
PROBLEM:
When processing satellite code, sometimes IDL bombs out with the
following message:
Loop over image
% Unable to free memory: from array descriptor.
Interrupted system call
% Execution halted at: PROC_TAU 1634
/home/kknapp/work/lib/idl/goes/gasp9.pro
IDL> .c
However, when I type .continue (above), it will keep running like no
error happened, therefore, something seems fishy.
This error only started happening after the upgrade. Same code. Same
data being processed. Same machine.
This problem has happened in my code .. in IDL-supplied code (that is
it's not necessarily my code that is broken).
It rarely crashes at the same point in the code.
I cannot reproduce it on demand, so I can't provide much of an
example.
Any help would be greatly appreciated!
