/evolution of the built-in command with the same name, you'll have to increase the spawn stack size anyway !?!? But that's for you pros to decide. At least seems you got a communication problem here, because nobody had a notion about the impact of Chaos commit.  Thanks to all & BR,

OK I already saw that simply increasing the heap is no solution, because it's already maximum size:  mm_initialize: Heap: start=0x20008924 size=227036    mm_addregion: Region 1: base=0x20008924 size=227024 -- Florian Wehmeyer TFW Tech-Solutions On Seg, 2020-05-

heap malloc when executing binary/elf file

Hi all,  again a question related to the execution of external / elf programs:  When I use malloc within the running elf program, allocating more than 1K bytes, malloc seems to work (doesn't return NULL), but when I use that memory (memset) I get a assertion/Kernel panic.. Funnily this does not
