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 ...
Re: Why does my heap_caps_malloc() crash? PostbyESP_igrr»Tue Oct 25, 2022 4:45 pm But that causes a Guru Meditation error: From the panic handler output, this looks like an attempt to write to a NULL pointer (https://docs.espressif.com/projects/esp ... prohibited). Could you...
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...
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 ...

If the user sets a string name, malloc it. In lv_obj_id_compare do a string compare (if the ID is not set generate it on the fly) I see two issues with it: If there are 2 button ("button1", "button2"), and the IDs are not set, and the first button is deleted, "button...

The analyzer has detected a user serialization method that does not meet the interface′s requirements. If the user serialization fails to meet the requirements, the Serialization API ignores it.
