Can we use awk to seed the rng?

$ for i in `jot 20`;do echo '#!/usr/bin/awk' | awk '/^#! ?\/.*\/[a-z]{0,2}awk/ {sub(/^#! ?\/.*\/[a-z]{0,2}awk/,"#! awk"); print}'; done
#! awk

awk: nonterminated character class ^#! ?\/.*\/[a-z]{0,2
source line number 1
context is
/^#! ?\/.*\/[a-z]{0,2}awk/ {sub(/^#! ?\/.*\/[a-z]{0,2}awk/,"#! >>> awk") <<<

No change with -fcommon, no change backing out recent awk commits.
If I change it to use gawk it builds reliably.
