[Bug 928900] Re: Segmentation fault with associative arrays

[Daniel Manrique]

Confirmed with importance: Medium as it is "A bug that has a moderate
impact on a core application. "

This script will reproduce (I changed the associative array's key to
"baz" to avoid confusion with the function name (foo)).

TEST CASE:

Run the following BASH script:

#!/bin/bash
function foo {
    declare -A hash
    declare hash[baz]=bar #bash crashes here
}

foo


Expected result:
nothing, but not a crash either

Actual result:
Segmentation fault

Title:
  Segmentation fault with associative arrays

Status in “bash” package in Ubuntu:
  Confirmed

Bug description:
  If we write code like:

  function foo {
      declare -A hash
      declare hash[foo]=bar #bash crashes here
  }

  Bash crashes when calling this function.  The same exact code works as
  expected if it's not in a shell function.
