In theory, yes. Could you send me the data + a script, please?
I've just fixed a probably relevant bug in CVS. If "catch" is
used in a loop, and it applies to a genr expression which gets
compiled, then the "catchiness" was wearing off after one go:
on the second or subsequent execution of the given compiled
line the error would not be trapped.
