php-7.1.12/ext/pcre/pcrelib/pcre_study.c:1372:35: warning: ‘<<’ in boolean context, did you mean ‘<’ ? [-Wint-in-bool-context]

Source code is

     if ((map[c/8] && (1 << (c&7))) != 0)

maybe better code

     if ((map[c/8] & (1 << (c&7))) != 0)

Not a PHP bug.

The typo was fixed in PCRE 8.39 (PHP 7.1 uses 8.38) but in their own words it "could not actually affect anything" anyways.

Note that PHP 7.2 uses PCRE 8.41 and PHP 7.3 will bring a switch to PCRE2.
