(Is there a more suitable newsgroup for this?)

Observed using gawk 2.02 beta (compiled for the IBM PC, not that that
should make any difference (?), and downloaded from SIMTEL):

Dynamic regular expression space seems not to be reclaimed, which
causes programs to run out of memory unnecessarily.

My program does the following for each input line:

{ if ($0 ~ r) {somestuff}
  else {someotherstuff}
}

r is a constant regexp passed from the command line, but it seems
to be recompiled at each use, and the space is not reclaimed, thus
causing execution to abort through lack of memory after 1100 lines
of input.  The same script, run with MKS awk, happily processes
18K lines of input without a problem.

Has this been fixed?  Is there a better way to write the script?
Is there a way to tell awk that r is constant?
