[bug-gawk] bug - slash in regexp with character classes

[Janis Papanagnou]

Is this a known issue...?

$ awk '/[/[:alnum:]]/'
# okay

$ awk '/[[:alnum:]/]/'
awk: cmd. line:1: error: Unmatched [, [^, [:, [., or [=: /[[:alnum:]/

$ awk --version
GNU Awk 4.1.2, API: 1.1 (GNU MPFR 3.1.0-p3, GNU MP 5.0.2)
