Fwd: gawk core dumped on too many input values

[Ed Morton <mortoneccc@comcast.net>]

This (original email below) turned out to be a general cygwin issue, not 
a gawk issue:

$ LC_ALL=C sed 's/x/y/' $(seq 1000000)
Segmentation fault (core dumped)

$ LC_ALL=C grep 'foo' $(seq 1000000)
Segmentation fault (core dumped)

Regards,

     Ed.

Gawk Version: 5.2.2

Attestation 1:
         I have read 
https://www.gnu.org/software/gawk/manual/html_node/Bugs.html.
         Yes

Attestation 2:
         I have not modified the sources before building gawk.
         True

Description:
         I was trying to test something related to ARG_MAX when I ran the
         awk script below and it core dumped instead of reporting an error
         and exiting gracefully. In case it's useful getconf ARG_MAX outputs
         32000.

Repeat-By:
         $ LC_ALL=C awk 'BEGIN{print ARGC}' $(seq 1000000)
         Segmentation fault (core dumped)
