If I try to set MEMP_MEM_MALLOC, I have some strange problems.
I suspect threading issues. I checked on win32 and it seems to work
fine. In the end, there's not really much lwIP does here, everything
is delegated to your C library's malloc code. Maybe that code isn't
thread-safe? In that case, you need to define mem_clib_*() to wrapper
functions that protect the heap.
I'm using NewlibNano as C library. However I'm using NOSYS=1 and I don't
use threads. In my application, "threads" are only interrupt service
routines, but I don't call mem_malloc from any ISR (I don't think lwip
uses interrupts at all).
So I don't think it is caused by a threading issue.
