I'm running Mac OS Catalina. ARG_MAX is 262,144 chars.
{noformat}
$ getconf ARG_MAX
262144
{noformat}
On Linux it is considerably larger:
{noformat}
getconf ARG_MAX
2097152
{noformat}
which is I suppose why hitting this is uncommon.
I don't think anything can be done without dev of the API checker itself.
Perhaps if it is still being maintained someone else has hit this and there is
a fix available. If not I could raise a PR. Practically speaking, this is not
super critical because Linux environments will continue to work.
