What's the best way to debug unexpected test failures? Does FunC have a print function? My test failed on first check: throw_if(100, exit_code != 0); but how I can receive exit_code to figure out what happened?

You're looking for the dump_stack() function.
https://ton.org/docs/develop/func/stdlib/#dump_stack
It dumps the last 255 values in the stack and shows the total stack depth.
() dump_stack() impure asm "DUMPSTK";
There's also the ~dump and ~strdump built-ins.
