Calling money_format with an apparently correct format


  setlocale (LC_MONETARY, 'en_US');
  echo money_format ('%#.2n', 1000);


causes PHP to hang (tested with 4.3.1 and 5-dev).

Apparently, strfmon() returns -1 (errno is 22, indicating an invalid parameter) even though the format should theoretically be correct. The -1 is not trapped in strings.c, resulting in a huge string full of binary data being returned.

Here's my suggested patch, returning false on an error from strfmon().
