(Referring to https://savannah.nongnu.org/bugs/?27235)
Do we have an English version of the page referred in the bug report? http://www.mikrocontroller.net/topic/147150 (The site embdev.net has a different forum) Specifically, I am trying to understand 2nd issue reported here. [quote] 2. If there is RAM for the Heap, which has been allocated and freed before, the next allocating goes from upper to lower addresses. This will IMHO be bad for realloc calls, because the memory behind will most likely be used, resulting in gaps if the memory size decreases and memory copies if increased." [/quote] How does allocation happen from upper to lower addresses? From what I understand, malloc resorts to heap expansion using __brkval which is the largest address not allocated so far. Thus it appears that allocation in a heap happens from lower to upper address. Let me know if I got something wrong.
