Apointer to pointeracts similarly to an ordinary pointer, except that it modifies the actual value associated with the pointer to which it points. To put it another way, the memory address held in an ordinary pointer is capable of being changed. Let’s consider a simple example: intn=10; ...
It turns out there's a silly debate about the right thing to do, and it hasn't been resolved, so technically allocating zero bytes is implementation-specific behavior. One side thinks that malloc(0) should return a null pointer and be done with it. It works, if you don't mind a ...
If the previous-frame structure memory had been a calloc() instead of malloc(), there would have been no problem, since the PROBE,R instruction would return false for a null pointer. The fix, as I understand it, was to add one line of code when entering U_get_previous_frame(): previ...
4) Your problem isn't even with the rlimit per se -- but data corruption or pointer truncation. Just because tmp is NULL doesn't mean that an allocation failed -- did malloc/new explicitly fail? Is there an error? 5) You've hit some fun issue with 2Gb vs. the ...
Are you using a data cache? If so, you should be using the IO macros and/or the bit 31 override to circumvent the cache. Alternately, you can use alt_uncached_malloc, which will return a pointer to an uncached location in memory. There are examples of this exact usage in the memtes...
