seems to work fine if using gawk, not mawk.

I'm experiencing this too, it seems to be caused by 6f53237
mawk only accepts a two-argument from of match()

Still doesn't work either with mawk or awk:
Using of -d seems to enable mawk in bash script.

Ubuntu 2020, perf-tools-unstable/focal,focal,now 1.0.1~20200130+git49b8cdf-1ubuntu1 all [installed],
Kernel: 5.4.0-52-generic

UPDATE: installing gawk via apt and hardcoding use=gawk in opensnoop-perf bash script seems to solve issue.
