I used the most recent version, 1.3.4-20230525, but I cannot reproduce the 
error (on macOS) even with 1.3.4-20200120. These two versions produce identical 
output.

mawk -Wversion prints:

mawk 1.3.4 20200120

regex-funcs:        internal
compiled limits:
sprintf buffer      8192
maximum-integer     2147483647

Note the sprintf buffer size, the same as in the error message when mawk fails 
on emba.

There may be something more than just a buffer limitation here. I don't know if 
the sprintf buffer is used for more than literal calls to sprintf, but they all 
seem to be small and well-behaved.
