Re: gawk 3.1.4 core dump

[Ed Morton]

Arnold - I don't know how it was compiled, it's part of a package 
maintained by a tools group at work. I'll try to twist their arm to move 
to gawk 3.1.5 as you suggest but that could take some time. I do get the 
same result with gawk 3.1.4 under Cygwin on Windows XP so I suspect it 
isn't a compilation problem:

$ cat t3
text /
$ gawk -vRS=" /( |$)\n" '1' t3
gawk: cmd. line:1: fatal error: internal error
Aborted (core dumped)
$ gawk --version | head -1
GNU Awk 3.1.4
$ uname -a
CYGWIN_NT-5.1 your-wg5n33dutv 1.5.12(0.116/4/2) 2004-11-10 08:34 i686 
unknown unknown Cygwin

Regards,
