Re: [lwip-users] UDP server on LwIP socket falls into hard fault if input string, longer than 19 bytes

That you for reply. I know about asserts. In debug version I use them to catch 
critical errors, and non-critical too. And I always enable all asserts in 
submodules. I also know about that article and had implemented most of their 
suggestions. That did not help this time.
I fixed the problem 
    
    #define MEMP_MEM_MALLOC   0 //was 1

I prefer dynamic memory allocation. But this time it doesn't work fine....

SOLVED.
