GnuWin32 gawk (2004-06-02 09:08, 306,688 bytes) ignores case if using a "/pattern/" with a [characterset], and programs with abnormal termination if the gawk variable IGNORECASE is properly set.

Screen dump displays comparison with UnxUtils gawk, a same version level:

---END CONSOLE DUMP-----

The GnuWin32 version of gawk should not have printed "FOO" in the command above, and should support the gawk variable IGNORECASE.

    Eric-
    Thank you so much for posting this. I've been working for weeks trying to nail down this elusive, erratic problem. My awk scripts would work fine on Win2Kpro, most of the time; hardly every work completely on XP. I was getting the same error message as you and an exit code of 3. When I commented out the IGNORECASE=1, my scripts became robust again on both of these operating systems. Thank you again!!!
