If rand() gives you trouble who knows what else in the C library may give you more trouble. It’s not that hard to copy paste or even write your own implementati

Newlib is open-source. For embedded projects, I find myself reading the source code to Newlib, and sometimes looking at the disassembly to double-check what version of a function I’m getting. If I had gotten burned by having malloc included when I didn’t wanted (never happened to me personally), I would consider running "ar d" to remove it from the copy of the library I’m using. It’s pretty easy to modify static libraries. > For me I’ve found GitHub Copilot great for filling in basic stubs for C stdlib APIs. I might want a decent implementation of snprintf, might want some decent implementation of memcpy/memset/memmove. I’ve implemented all of these myself, but it’s a pain, and I generally would rather grab Newlib rather than trust Copilot.
