For the following code:
#include <stdio.h>
int main(void)
{
__asm__("int3");
// give code to step through
for (int i = 0; i < 10; ++i)
{
printf("%d\n", i);
}
}
Compiled with:
gcc -o int3 -g3 -O2
When I try debugging under GDB 13.2, I get the following:
0x7fb54815cd89 ???
0x558eebc578e4 ???
0xffffffffffffffff ???

`pc_in_thread_step_range (pc, tp)' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

This is a bug, please report it. For instructions, see:
<https://www.gnu.org/software/gdb/bugs/>.
This instruction seems to be the standard way to implement a breakpoint
from code.
Clang has an intrinsic __builtin_debugtrap() which generates it, and
Microsoft Visual C++ generates it from __debugbreak().
