Hi guys,

my node.js app is crashing randomly and rather rarely and gives me the 
following stack trace...

Program terminated with signal 11, Segmentation fault.

#0  0x5e02190a in ?? ()

(gdb) bt

#0  0x5e02190a in ?? ()

#1  0x5e01316a in ?? ()

#2  0x08210303 in v8::internal::Invoke(bool, 
v8::internal::Handle<v8::internal::JSFunction>, 
v8::internal::Handle<v8::internal::Object>, int, 
v8::internal::Handle<v8::internal::Object>*, bool*) ()

#3  0x0821062f in 
v8::internal::Execution::New(v8::internal::Handle<v8::internal::JSFunction>, 
int, v8::internal::Handle<v8::internal::Object>*, bool*) ()

#4  0x081bfadd in v8::Function::NewInstance(int, v8::Handle<v8::Value>*) 
const ()

This crash is actually produced by a code written in C++ and running as 
node extension. I was able to decrypt that the call to 
v8::Function::NewInstance is actually a call to node's builtin Buffer 
constructor which is a pure JS code.

What strategy can I use to decode where the JS code could be actually 
crashing?

The bug is not reproducible but happens under heavy load randomly...

thanks for any pointers,
Martin
