agentzh / e-tok-deref-fix.patch
Created October 19, 2018 23:53
commit 78c9a67ec4e487058c215136594d4bbfe6185ca0
Author: Yichun Zhang (agentzh) <yichun@openresty.com>
Date: Wed Oct 3 20:20:26 2018 -0700
bugfix: a NULL deferef crash might happen in const_folder::visit_binary_expression() due to the fact that e->tok might be NULL.
It is still not clear why e->tok would end of being NULL in the first
place. Need investigations by tracing the full stap AST with stap (or
gdb). The core dump can be easily reproduced by running the pyftrace
ylang tool with 'stap -vvv' (and also without this patch).
