[lwip-devel] [bug #17922] mem_malloc bug

[Simon Goldschmidt]

Follow-up Comment #8, bug #17922 (project lwip):

>some bare-bone raw-API micro's simply don't have semaphores. 

Yes, but for raw-API-only you normally don't need to protect mem_malloc()
since you don't have multiple threads (and if you have multiple threads,
normally you have semaphores). The reason for this is that in interrupt
context (which in a thread-less design is the only source of parallelism),
only PBUF_POOL types should be allocated, so our heap is not touched.

Anyway, this is no problem for me, since I'm not using the heap. Just wanted
to point out a possible problem...
