Hello All,

I am involved with a project that relies on v8 for most of its features. We 
are trying to upgrade the v8 engine to 8.5 and the project compiles without 
any error.

We also have a debugger that uses inspector protocol -- however after the 
upgradation the debugger crashes when 
*session_->dispatchProtocolMessage(message); 
*is invoked.

I am relatively new to v8 and don't understand it completely, however I 
noticed that the implementation of platform, return values of Set, Get were 
changed between the versions(and the corresponding changes are made). I 
don't see any changes with respect to the inspector -- I am afraid I am 
missing something here. 

You can find our project 
here: https://github.com/couchbase/eventing/tree/master/third_party/inspector

Any help would be very much appreciated! 

The debugger crashes with the following message:
==============================================
# Fatal error in HandleScope::HandleScope
# Entering the V8 API without proper locking in place
#
== Minidump location: crash/cfecbc18-15f2-428d-a10256ac-40061e00.dmp 
Status: 1 ==
Failed to read from stderr pipe, err: EOF
Failed to read from stdout pipe, err: EOF
Exiting c++ debug worker with error: signal: illegal instruction
===============================================

Also the symbols in the coredump (after conversion from minidump to 
coredump) is not getting resolved. I see ????? for line numbers and 
function names!
