Memory leak in clGetPlatformIDs of SDK 2.9-1?

Running my ocl app through Valgrind in Linux I get:

There are numerous other warnings about clGetPlatformIDs in valgrind, but are much smaller in scope. Malloc seems to be in libatiadlx.so, can't tell if libatiadlx is responsible to free it or libamdocl64.

Re: Memory leak in clGetPlatformIDs of SDK 2.9-1?

Hi Nikos,

This seems to be an OpenCL/APP SDK related question -- seemingly not related to the Media SDK forum. I'll move it to the OpenCL forum.
