I sounds like the shebang is actually longer than Linux’s static limit.

Indeed, the string
is exactly 126 characters, but BINPRM_BUF_SIZE in Linux, which accounts
for the entire shebang plus trailing zero, is 128.

Commit b69c5c2 works around that by skipping tests that would otherwise
hit this limit.

I will also add configure-time checks to at least warn about the risk of
such problems.

Thanks for the report!
