I have a program exited with SIGTRAP and a core file dumped:

$ gdb test core
....
Program terminated with signal 5, Trace/Breakpoint Trap.


But there is no one to debug the process at the time.
Why is it core dumped? Does it mean there is a bug caused the core?

SIGTRAP was originally caused by the PDP TRAP instruction,
but these days its semantics are platform-specific.

General, something has gone wrong in your program.  :-)

Yes.
