Hello, all. I tried to use the gdb macro rtems_malloc_walk in my 4.8 - it fails with the error: "there is no member named front_flag". Tracing the issue, I found reference to this front_flag in the rtems_helper_score_heap. Structure of type Heap_Block really does not contain such a flag in 4.8 and nothing that can look similar to it. Any hints? Thanks. -- Leon
