PHP Bug Type: CCVS related
Bug description: ccvs_*() functions segfault when given invalid session ID
The ccvs functions segfault when given an invalid session ID.
This works fine:
<?php
$session = ccvs_init('ccvs');
echo "Adding an invoice to the session:\n";
if (!ccvs_new($session, 'foo') === 'OK') {
echo "Could not create invoice; reason: " . ccvs_textvalue($session) . "\n";
}
?>
This segfaults:
<?php
$session = ccvs_init('ccvs');
echo "Adding an invoice to the session:\n";
if (!ccvs_new($sess, 'foo') === 'OK') {
echo "Could not create invoice; reason: " . ccvs_textvalue($session) . "\n";
}
?>
