#25394 [NEW]: Segfault and Crash on long scripts.

From: mark dot meredith at shaw dot ca Operating system: MAC OS 10.2.6 PHP version: 4CVS-2003-09-06 (stable) PHP Bug Type: Reproducible crash Bug description: Segfault and Crash on long scripts. Description: ------------ I have tested this with the 4.3.2 and 4.3.3 official releases as well. I have not tried any earlier releases. I have tried with the command line or as an Apache 1 or Apache 2 module all with the same result. I used no extensions or modules for the builds in all cases. Apparently the bug does not occur for Windows XP Pro and likely some other operating systems. I was told this by some users of a PHP forum who tried their own test scripts. The result of memory_get_usage() placed on a script one line shorter than the crash length returned around 1MB. Thank you. Reproduce code: --------------- <?php /*presumably any long script that consumes enough memory will cause the problem*/ /*this assignment done about 10000 times*/ $x = 1; ?> Expected result: ---------------- Nothing but a clean run through. Actual result: -------------- The backtrace from the STABLE snapshot cli was...
