Package: valgrind
Version: 1:3.16.1-1
Severity: normal
Hello,
I don't seem to be able to use vgcore files in gdb any more:
(gdb version 10.1-2)
$ cat test.c
int main(void) {
*(int*)0 = 0;
}
$ gcc test.c -o test -g
$ valgrind ./test
[...]
$ gdb ./test vgcore*
[...]
Reading symbols from ./test...
[New LWP 1051166]
Core was generated by `'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x000000000010912e in ?? ()
(gdb)
While without valgrind:
$ ./test
zsh: segmentation fault (core dumped) ./test
$ gdb ./test core
[...]
Reading symbols from test...
[New LWP 1051373]]
Core was generated by `./test'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 main () at test.c:2
2 *(int*)0 = 0;
(gdb) p/x $pc
$2 = 0x55a04b9f812e
