<div dir="ltr">The only thing I can suggest is to use clang-query and start from the most basic matcher, say functionDecl, then gradually constrain it using hasName, etc. See at what point you get the crash. Reducing your input source might also help, if this is a Clang bug you'll have a minimal repro case. I've only tried my query on a super simple file.</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 12, 2015 at 11:36 AM, Riyad Parvez <span dir="ltr"><<a href="mailto:riyad.parvez@gmail.com" target="_blank">riyad.parvez@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I've tried your query and getting segmentation fault. I've tried to
get backtrace from gdb, but for some reason gdb is printing garbage.<br>
