Hi,

steps to reproduce:

$ printf "a"|awk '/[\x80-\x81]/ {count++}; END {print count}'

awk: cmd. line:1: fatal error: internal error: segfault

Aborted (core dumped)

or simply:

$ printf "a"|awk '/[\x7f-\x80]/'

awk: cmd. line:1: fatal error: internal error: segfault

Aborted (core dumped)

Used SW:

• Ubuntu 16.04 x86_64
• gawk --version: GNU Awk 4.1.3, API: 1.1 (GNU MPFR 3.1.4, GNU MP 6.1.0)

See the attached crashdump.

Is that relatied to this?:
$ printf "a" | sed -r 's/[\x7f-\x80]/#/'
sed: -e _expression_ #1, char 16: Invalid collation character


$ sed --version
sed (GNU sed) 4.2.2
