Found the source to malloc and it looks like the cause is the following code
inserted in AVR LibC 1.6.5:
if (cp <= __brkval)
/*
* Memory exhausted.
*/
return 0;
If I read this correctly, since the AVRX task stack is under __brkval,
malloc won't work if called from a task.
Maybe I can put a wrapper around malloc to repoint the stack pointer so that
this line is valid:
cp = STACK_POINTER() - __malloc_margin;
