It had the same name, ../sed/sed(.exe), but was a different
compilation.  The sed which had the first crash was build with the
supplied Makefile.  The package was reconfigured for NLS
and --host=i786-pc-msdosdjgpp.  This host thing did not cause
the build to use any extra flags.  The second crash was from
this sed.  I have no record of the size of the exe files.  As
the two differed in details, I made a third build with NLS
disabled.  It's crash was the same as the second's, reporting
ct_upper.c.
