How to print the last received signal in GDB?

when loading a core dump into GDB the reason why it crashed automatically is displayed. For example

Program terminated with signal 11, Segmentation fault.

Is there any way to get the information again? The thing is, that I'm writing a script which needs this information. But if the signal is only available after loading the core dump amd I can't access the information later on.

Is there really no command for such an important feature?

Solution

If you know what the core file name is, you can issue the target core command which respecifies the target core file:

(gdb) target core core.8577
[New LWP 8577]
Core was generated by `./fault'.
Program terminated with signal 11, Segmentation fault.
#0  0x080483d5 in main () at fault.c:10
10      *ptr = '\123';
(gdb)

As for the implied question, what is the info last signal command?, I don't know. There does not seem to be one.

The core file's name can be obtained from the command info target:

(gdb) info target
