Hi misc, I'm running a 5.7 release, and I'm wondering if anyone can confirm an awk bug I found.
Curly brackets are treated as literal characters instead of bounds
as specified by re_format(7).
Reproduction:
echo aa | awk '/a{2}/'
produces no output instead of printing "aa" as expected.
echo 'a{2}' | awk '/a{2}/'
produces output when none is expected.
This bug seems awk specific since the equivalents using grep
echo aa | grep -E 'a{2}'
echo 'a{2}' | grep -E 'a{2}'
work as expected.
