You can "set" a breakpoint this way in x86 Linux too. Unfortunately,
when this is not run under the debugger, it simply sends a SIGTRAP to
the process. In theory the standard library could handle SIGTRAP by
invoking the debugger, but 5 minutes fiddling around didn't produce a
very dependable way of doing so.
Starting program: ./a.out
Program received signal SIGTRAP, Trace/breakpoint trap.
main () at bp.c:21
#define BREAKPOINT _asm int 3
#elif defined(__GNUC__) && defined(__i386__)
#define BREAKPOINT __asm__ __volatile__ ("int3")
#warning "BREAKPOINT not defined for this OS / Compiler"
#define BREAKPOINT (void)0
#define _DEBUG (void)0
