Print current thread after loading a core file
downstream Fedora request:
Please make it easier to find the backtrace of the crashing thread
https://bugzilla.redhat.com/show_bug.cgi?id=1024504
Currently after loading a core file GDB prints:
Core was generated by `./threadcrash1'.
Program terminated with signal SIGSEGV, Segmentation fault.
8 *(volatile int *)0=0;
(gdb) _
there is nowhere seen which of the threads had crashed. In reality GDB always
numbers that thread as #1 and it is the current thread that time. But after
dumping all the info into a file for later analysis it is no longer obvious.
'thread apply all bt' even puts the thread #1 to the _end_ of the output!!!
Should GDB always print after loading a core file what "thread" command would
print?
[Current thread is 1 (Thread 0x7fcbe28fe700 (LWP 15453))]
BTW I think it will print the thread even when loading single/non-threaded
core file when other inferior(s) exist. But that currently crashes
[Bug threads/12074] multi-inferior internal error
https://sourceware.org/bugzilla/show_bug.cgi?id=12074
plus I think that would be a correct behavior anyway.
