#38775 [Fbk->Opn]: Segmentation Fault on CLI

ID: 38775 User updated by: iain at iaindooley dot com Reported By: iain at iaindooley dot com -Status: Feedback +Status: Open Bug Type: Scripting Engine problem Operating System: FreeBSD 6.1 PHP Version: 5.1.6 New Comment: okay, in my configure line i have --enable-debug. on the page with instructions to obtaining a backtrace, it says i need to compile --with-debug. will compiling with --with-debug instead of --enable-debug improve the backtrace? Previous Comments: ------------------------------------------------------------------------ [2006-09-11 08:17:05] tony2001@php.net >is this something incorrect i have done in my php script? > i don't know what ap_getline is. No, it's not about you or your script. ap_getline() is a function from Apache API, so it just can't appear in CLI. ------------------------------------------------------------------------ [2006-09-11 08:16:51] mike@php.net Because ap_getline() really looks like an Apache httpd internal function. Anyway, you can produce much better backtraces with a debug build. Thanks. ------------------------------------------------------------------------ [2006-09-11 08:03:29] iain at iaindooley dot com okay, i'll put a script into cron that doesn't do much and see if it segfaults. i'm a bit mystified by the last line of the comment: "ap_getline () in CLI? Something is really broken there." is this something incorrect i have done in my php script? i don't know what ap_getline is. the scripts that are producing this problem are largish applications. based on the information available do you have any suggested content for a script to test on the command line? ------------------------------------------------------------------------ [2006-09-11 07:36:48] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ap_getline () in CLI? Something is really broken there. ------------------------------------------------------------------------ [2006-09-11 06:46:07] iain at iaindooley dot com i followed the instructions on obtaining a backtrace, however the backtrace i received does not seem to be as helpful as the example: ---Type <return> to continue, or q <return> to quit--- #385 0x00000001 in ?? () #386 0x283303d8 in ?? () #387 0x28317cdd in ?? () #388 0x08066bc4 in ap_getline () the previous lines (of which there are many) are all similar to the three above ap_getline, ie. they all have an address and ?? () i checked my config, and i ran ./configure with --enable-debug. i notice on the page with instructions to obtain a backtrace it is --with-debug. is there a difference? a different application on the same machine that also runs scripts on the command line had this backtrace: #2464 0x0000008c in ?? () #2465 0x0838c950 in ?? () #2466 0x00000000 in ?? () #2467 0x28316cdd in ?? () #2468 0x08064280 in ap_cfg_getline () Previous frame inner to this frame (corrupt stack?) once again i have ommitted many lines above that were ??() ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
