[PHP-DEV] Bug #1953: Certain messages cause php3's imap functions to crash. From: online <email protected>
Date: 08/03/99

From: online <email protected>
Operating system: Linux 2.2.10
PHP version: 3.0.12
PHP Bug Type: Reproduceable crash
Bug description: Certain messages cause php3's imap functions to crash.

Certain messages cause php3 to crash when being accessed via imap. Both c-client 4.5 and 4.6.BETA from washington.edu compiled into php 3.0.12 produce the same result.

Please email me at online <email protected> if you need a test account with the message that causes this crash.

Here is a backtrace to help you audit and debug the code:
