Submitted: 2019-02-08 19:36 UTC Modified: -

Description:
------------
If ini string has numeric sections and INI_SCANNER_TYPED options is used, then i get segmentation fault.

But if numeric sections are enclosed in quotes (["0"], ["1"], etc) then no problem occurs.

Test script:
---------------
var_dump(
    parse_ini_string(
        <<<INI
[0]
a = 1
b = "2"
c = true

[1]
a = 0
b = "abc"
c = false
INI,
        TRUE,
        INI_SCANNER_TYPED
    )
);


Expected result:
----------------
array(2) {
  [0] =>
  array(3) {
    'a' =>
    int(1)
    'b' =>
    string(1) "2"
    'c' =>
    bool(true)
  }
  [1] =>
  array(3) {
    'a' =>
    int(0)
    'b' =>
    string(3) "abc"
    'c' =>
    bool(false)
  }
}


Actual result:
--------------
Segmentation fault
