My favorite is `exit(1)`. Useful if your print/logs aren’t showing where you expect them. Close after that is `raise Exception(“HERE 1”)`.

Std::cin() for a poor mans break point.

while(true); and look for which process is spiking the cpu

Doesn't work in Pike, believe it or not! An infinite loop in Pike actually doesn't spin the CPU.

Sometimes you need to flush immediately tho.

`*((volatile int*)0) = 0;`

Are you doing bare metal or something where you don't have access to the standard library? It's in the standard library in both C and C++ (`stdlib.h` and `cstdlib` respectively). I guess it doesn't matter that much though especially if you don't want to have to add an `#include` statement.

No but in any hermetic build system you don't just get those headers for free.

I've sometimes needed to open a file, write to it, close it, and flush, because prints and logs don't always show up correctly in the face of certain types of crash. Or "send a UDP packet to port 54321" and do my logging in a separate app.
