Hi, I've read that PHP compiled in debug mode was supposed to warn of memory leaks. I've tried to add an obvious memory leak, but got no messages: (...) void *a = emalloc(200); printf("%d", *((int*)a)); (...)

php.exe -i | findstr cscript

Configure Command => cscript /nologo configure.js "--enable-debug" "--enable-crt-debug" Did I do anything wrong?

Do you have report_memleaks = On in your php.ini?

Now I do, but it didn't help.

I would also suggest using valgrind to detect memleaks, but don't forget to --enable-debug and export USE_ZEND_ALLOC=0 env var. Here is the line I use: USE_ZEND_ALLOC=0 valgrind --tool=memcheck --leak-check=yes --num-callers=30 --show-reachable=yes php script.php

There's no valgrind for windows. I already lost 2 hours with this. I'll try the windows internals list tomorrow. Thanks anyway -- Gustavo Lopes
