Summary	0000425: memory leak (around 40MB for each request) when using xdebug_start_trace
Description	When running the following code xdebug leaks 40MB of memory. code start; xdebug_start_trace(); // 1 {code to trace } echo xdebug_peak_memory_usage(); // 2 xdebug_stop_trace(); // 3 code end; Memory allocated by the above request is never returned to the heap. As a result first the heap gets full and then the swap file, which results in a auto restart of the machine. One remedy to this problem is actively monitoring the apache server an restarting when it consumes to much memory which is a temporary solution. Memory leak doesn't happen when you comments the lines indicated bij 1,2,3.
