/**
 * G_BREAKPOINT:
 *
 * Inserts a breakpoint instruction into the code.
 *
 * On architectures which support it, this is implemented as a soft interrupt
 * and on other architectures it raises a `SIGTRAP` signal.
 *
 * `SIGTRAP` is used rather than abort() to allow breakpoints to be skipped past
 * in a debugger if they are not the desired target of debugging.
