Could you explain why?

I am not sure that applying this patch is ok.  It is generic code, so
this change may negatively affect other languages -- it is hard to be
sure without replicating your analysis.

Perhaps some other Pascal-specific fix would be more obviously safe.

Do you have copyright papers in place?  If not, contact me off-list to
get started.

Patches should go to gdb-patches and have a ChangeLog entry.
See gdb/CONTRIBUTE.

This seems iffy for C++.
