[lwip-devel] [patch #6528] lwIP crash with large ICMP messages.

[Simon Goldschmidt]

Follow-up Comment #6, patch #6528 (project lwip):

I just remembered why ram_heap is MEM_SIZE_ALIGNED + (2*SIZEOF_STRUCT_MEM) +
MEM_ALIGNMENT: I wanted the user to be able to allocate MEM_SIZE at minimum.
And since we need one struct mem at the start and one at the end, we need
2*SIZEOF_STRUCT_MEM. Ok, maybe '+ MEM_ALIGMENT - 2' would be enough, but those
2 bytes... We can change that, but I prefer it the way it is now.
