On 64bit windows casting a pointer to a 32 bit int will truncate that pointer. This kind of things won't work on Windows x64. [SNIPPET] unsigned long ul0[2], ul1, *ul2; ul0[0] = 42uL; ul0[0] = 24uL; ul1 = (unsigned long)ul0; ul2 = (unsigned long *)ul1; /* now it's broken, accessing ul2[0] will crash. */ [/SNIPPET] To make it portable, ULONG_PTR should be used in this case. In oniguruma this behaviour is to see at least in the following codepath: ext/mbstring/oniguruma/enc/unicode.c:10938 ext/mbstring/oniguruma/st.c:308 ext/mbstring/oniguruma/enc/unicode.c:10859 Bugs: https://bugs.php.net/64769 Changed paths: M NEWS M ext/mbstring/oniguruma/oniguruma.h M ext/mbstring/oniguruma/st.h Diff: diff --git a/NEWS b/NEWS index 0cb524a..eeff8e7 100644 --- a/NEWS +++ b/NEWS @@ -22,6 +22,9 @@ PHP NEWS .
