New issue 2486 by [email protected]: --print-ast and --print-source
segfault with throw statements
http://code.google.com/p/v8/issues/detail?id=2486
With r13362 (today's HEAD):
$ cat test.js
throw 42
$ out/x64.debug/d8 --print-ast test.js
<snip>
*** Generate code for user-defined function: KeyedLoadElementStub ***
Segmentation fault (core dumped)
Ditto for --print-source. The patch below works around it but doesn't
address the root cause, i.e. _why_ program == NULL.
