PHP Bug Type: Reproducible crash
Bug description: PHP CGI Crash After Expected Output Produced
Description:
------------
Windows x64 + Apache + PHP CGI
Using ODBC to access MSSQL database.
After running a script with many queries using PEAR DB_DataObject, PHP
crashes. I do not believe any particular code snippet is causing the
problem, but it seems to involve the number of allocated objects. PHP
seems to be crashing after the entire script has been executed. After
setting
implicit_flush = On
in php.ini, the entire expected output is produced. The call stack looks
like the crash is happening during decreasing the reference count of an
object ...?
The same code does not crash PHP 5.0.5. It does seem to crash all 5.1.x
versions.
Actual result:
--------------
Unhandled exception at 0x10099bf7 (php5ts.dll) in php-cgi.exe: 0xC0000005:
