One year later .... (with the same/latest version)
Using :
set -x
set -v
in a script generates a similar error around line 50whatever code I put in the
script

Thanks for the report. However:
I have no hope of reproducing this, do I?
AFAICS, the few changes from 5.2.14-2 to 5.2.14-3 that could have possibly
caused this are the fixes in the autoconf files. I doubt the "struct
option" magic would matter, but it's possible, I guess, though by
eyeballing the code the two versions do look functionally equivalent.
It would help to have a script that demonstrates the problem. I can't do
anything otherwise, sorry...
