y decreases. You can have situations where most of the heap is free, but it can't be shrunk because some chunk at the top of it (near y) isn't free; in this case, the process hogs a lot of memory it doesn't really need. Alternatively, the malloc and free could just decide to ...

It does not use malloc/free since the size is defined as a template parameter and is written in plain C++98 with no special features used.SponsorsHow to use it.Once a block has been used you must Skip() the buffer the number of reads you made, this is so that writing to the buffer...
Additionally information: It seems the real problem was the option "CONFIG_SPIRAM_USE_MALLOC=y". With this option enabled, my apps are crashing (=CDC not booting). I am running arduino as component and mixing C++ with C/ESP-IDF - maybe this could be the problem with malloc. I switched...

I would say, technically, none of C++ I/O streams use buffering by default (when sync_with_stdio is on) - not std::cerr, not std::cout, They both immediately transmit every single byte written to the corresponding C I/O stream (stderr, stdout). *those* streams are what's fully/li...
Thank you Steve, on windows i use MVS IDE where i can easily set the libraries to be static. On Linux i use a terminal where i give the command: ifort -mkl -qopenmp source.f90 -o output i guess from your reply this command does not specify the library to be static. I would be ...
If necessary, you can consider switching to use Newlib/NewLibNano. The specific switching method can be seen in the figure below. To further determine whether it is a malloc issue or a static buffer issue, you can try to track the memory usage, analyze the changes of memory data before ...
