the line number of js in js frame is wrong

[phantom9999]

there is something wrong with the line number of js, when i use 'v8 bt' to find while line do coredump.
for example, while run this file, node coredump:

1.  function aa() {
.
.
12.    // coredump
.
.
.
}

use 'v8 bt', it will show node coredump at the line of function(line 1) not the line of running(line 12)
