Validate Hook causing PHP memory errors

[bpmccain]

I'm stumped on this one, primarily because it was working earlier today and now its not. I've gone back to backups, and still nothing.

I use the validate hook to validate certain form entries in profiles (such as phone number). Today, when I start submitting forms with errors, I am getting a Server Error, which is showing up in my logs as:

Code: [Select]

PHP Fatal error:  Allowed memory size of 536870912 bytes exhausted (tried to allocate 62914560 bytes) in /sites/all/modules/civicrm/packages/Log.php on line 554, referer: https://example.com/civicrm/contribute/transact?reset=1&id=2
I've gone back to basics to find out what the cause is.

This works fine, as it should, and processes the form.

Code: [Select]

function nbla_hooks_civicrm_validateForm( $formName, &$fields, &$files, &$form, &$errors ) {
    return $errors;
}

This doesn't, and gives me the Server Error noted above.

Code: [Select]

function nbla_hooks_civicrm_validateForm( $formName, &$fields, &$files, &$form, &$errors ) {
    $errors['postal_code-1'] = ts( 'Please enter a valid postal code' )
    return $errors;
}
If I put in a backtrace right before Line 554 in Log.php, I get the following. I have greatly shortened the queries as they are actually several thousand lines long. Also not sure why the backtrace is being displayed twice.

Code: [Select]

Update, it only appears to apply to CiviContribute. I see someone else with a similar problem.
