I tried gdb backtrace 'bt' command with the new core by v6.0, and it
doesn't show the call trace correctly. Is it related to this commit?
test program
----------------------------------------
void f(int n)
{
printf("%d\n", n);
if (!n)
kill(getpid(), SIGQUIT);
f(--n);
}
int main(int argc, char *argv[])
{
f(atoi(argv[1]));
return 0;
}
----------------------------------------
ulimit -c unlimited
coredump 2
gdb coredump core
bt
----------------------------------------
expected result
kill
f
f
f
main
----------------------------------------
actual result
