The standard way to escape % in a printf is with %%; although \\%zu
seems to have worked in awk until recently, an upgrade on Fedora 36
has started failing:
awk: cmd. line:1: (FILENAME=- FNR=1) fatal: not enough arguments to satisfy format string
'printf("sizeof(%s) = \%zu\n", sizeof(%s));
'
^ ran out for this one
Switching the escape to "%%" fixes this for me, and also works
on my very old RHEL7 mcahine.
