Use cygwin / gcc?!?! :P
Is debug_backtrace() unable to give you what you want?
<?php
$old_err = set_error_handler('bt_handler');
trigger_error();
restore_error_handler();
function bt_handler($type, $msg, $file, $line) {
return debug_backtrace();
}
?>

actually, this isn't related to the php language itself, but more to the
code beneath it ;)
Since the entire php/apache process segfaults (according to the logs), I
can't do a debug_backtrace() from within php :)

Do you get a windows dialog with "this application did something really
bad..."?
If you do pressing "Cancel" should start the debugger automatically. You'd
need to compile php in the debug mode in order to get some useful
information out of it though.

which simply tells me PHP started up fine, transfered control to Apache,
and then died :|
So... that would point to a bug in apache, right?

hello,
I've compiled PHP (and apache) on windows (using MSVC++.NET), and have
been doing so for a while now. Lately I've noticed Apache crashing when
I run certain scripts, so I figured I'd best make a backtrace in such
cases (since the scripts it crashes on are pretty long and complex, so
getting to the code that makes it crash is pretty hard). However, I'm
unsure how I can backtrace what hapenned before it crashed. I've tried
using the gdb (GNU Debugger), but it returns only "??" for each item in
the stack, even though PHP itself is built with debug symbols. Maybe
apache should aswell?? I'm not sure how to continue here... =/
Does anyone have any tips/advice? (except for the "get a precompiled
snapshot from php.net one)
thanks,

hi all
Does anyone have debug map files for the release version of php 4.3.10?
I'm getting a semi-intermittent access violation, but I don't have
access to MSVC to build the debug versions of the dlls.
thanks!
btw, in case this looks familiar to anyone, here's the info I have about
the crash, which happens every few requests, particularly it seems on
reloading pages generated after a POST.
Windows XP pro SP2
Apache/1.3.33 (Win32)
PHP/4.3.10
stack trace:
7C910C27 C:\WINDOWS\system32\ntdll.dll
7C910D5C C:\WINDOWS\system32\ntdll.dll
77C2C2DE C:\WINDOWS\system32\msvcrt.dll
77C39AE9 C:\WINDOWS\system32\msvcrt.dll
77C35F5D C:\WINDOWS\system32\msvcrt.dll
77C35FEC C:\WINDOWS\system32\msvcrt.dll

Hi Edin,
Indeed that may be the case! However, there is a Win32 port for QDBM
that I downloaded from qdbm.sourceforge.net which includes dlls, header
files to compile qdbm support into win apps, and comes with DOS apps
that can create, access and test qdbm files. This may be a new addition
to the QDBM binaries.
I just need to now find out how to get PHP's dba extention to support it
too!
Thanks :)
Justin
