Bug Type: Reproducible crash
Operating System: Windows XP Home, SP2
PHP Version: 4.4.2
New Comment:
Backtrace without debug symbols doesn't make any sense.
And yes, your debugger points to a wrong place.
Please try to reproduce it on *nix and get a valid backtrace with GDB,
if MSVC is unable to give you requested information.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Description:
------------
PHP 4.4.3.3 from snaps.php.net (php4-STABLE-200604220230), as well as
'official' PHP 4.4.2 available in the 'Downloads' section of php.net
crashes with the following message:
####################### cut here #################################
AppName: php.exe AppVer: 4.4.3.3 ModName: ntdll.dll
ModVer: 5.1.2600.2180 Offset: 00010f2b
Unhandled exception at 0x7c910f2b in php.exe: 0xC0000005: Access
violation reading location 0x0009000d.
####################### / cut here #################################
My system is XP Home SP2, Apache 1.3.33
Bug reproduces all times when I open one PHP script (can't reproduce it
here since it is a part of large obfuscated project of other developer;
you can download it here:
http://e2.ilyabirman.ru/download/e2_oranda_te_v1454_distr.zip,
126Kb).
Doesn't reproduce on PHP 4.3.11. mod_php is affected as well as CGI
version.
Crash is caused by the wrong setting in php.ini:
valid example:
include_path = ".;c:/path/with/some/cyrillic/letters/"
example that causes PHP to crash:
include_path = "c:/path/with/some/cyrillic/letters/"
Reproduce code:
---------------
Code that demonstrates the crash:
http://e2.ilyabirman.ru/download/e2_oranda_te_v1454_distr.zip,
126Kb
Expected result:
----------------
PHP should report or just ignore the wrong setting, not to crash.
Actual result:
--------------
MS Visual Studio 2003 EA debugger displays the following:
####################### cut here #################################
malloc.c, line 212:
#ifndef _WIN64
if (__active_heap != __SYSTEM_HEAP)
size = (size + BYTES_PER_PARA - 1) & ~(BYTES_PER_PARA -
1);
#endif /* _WIN64 */
return HeapAlloc(_crtheap, 0, size);
} // <== THIS IS LINE 212
#else /* WINHEAP */
/* try to find a big enough free block
*/
