Hello Guys!

I have an error related to test_memory_buffer_allocator on the server in my PR (https://github.com/ARMmbed/mbedtls/pull/4140). Tried to find the issue locally on both the latest Ubuntu and on version 16.04 (same as on the server), but without success.
All the tests pass if I run "make test" command (of course I changed config.h based on the component in all.sh)..
I have also tried:
"./tests/scripts/all.sh component_test_memory_buffer_allocator", but it does not do anything, just lists some tools. Maybe I am not using it right...

The memory allocation/freeing mechanism was not touched by my changes except that in the function that frees a CRT I added a small part to free the new dynamic field.

Do you have any idea what's wrong with my PR, how could I solve it or find out the cause?

Thank you guys!

BR,
Gábor
