The memory leak was caused by a bug in function setlocale on FreeBSD: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243195 The fix is the following: * Remove the calls to setlocale when formatting the result. * The function snprintf is still called, and then is now locale dependent, for example in French the decimal separator is a comma instead of a dot. * A new function calc_sanitize_decimal_number is introduced to "sanitize" a decimal number: keep only the decimal separator (replace it by a dot) and remove any other separator found. Unit tests are added on these functions: * calc_sanitize_decimal_number * calc_format_result
