Here's a backtrace and disasm which suggests that it is related to this (i.e. missing an 'endbr64' landing pad at the program counter location) though there are other endbr64 in the disasm. Looks like this is coming from the coroutine code in kicad which uses a copy of libcontext https://gitlab.com/kicad/code/kicad/-/blob/master/include/tool/coroutine.h https://gitlab.com/kicad/code/kicad/-/blob/master/thirdparty/libcontext/libcontext.cpp I'll try a build with USE_NOBTCFI which should help, I'll commit that if it works. (That doesn't stop someone delving into the asm if they want). Core was generated by `kicad'.
