This turned out to be (who would have guessed!?) a
programming error. And for years we have been lucky,
I guess.

Anyhow, in case anyone is following this, we weren't
using the built-in IDL string handling functions.
In our case, we had to change this code:

gcs->gpd_filename.s = grid->gpd_filename;
gcs->gpd_filename.slen = strlen(grid->gpd_filename);

to this code.

IDL_StrStore(&(gcs->gpd_filename), grid->gpd_filename);

That appeared to solve our problem.

Cheers,

David
