Comment 2 Vladimir Kvashin 2011-01-14 19:20:59 UTC 
I'm unable to reproduce this.

Code says the following.

The stack is just a result of assertion.

This might happen in the case file is removed from disk after the correspondent #include directive was resolved but before we started lexing the included file. 

So probably we should just remove the assertion.

However Alexander believes that no file was deleted during parse.
Comment 3 Vladimir Kvashin 2011-01-17 13:48:20 UTC 
This occurred once and nobody can repeat this; however I'd like not to close this issue; let's see whether this will repeat.

Anyhow, assertion should be softer (just a message in console).

Comment 5 Vladimir Voskresensky 2011-01-23 20:35:41 UTC 
Alexander was able to reproduce it, making back to P2 for deeper investigation, right?
Comment 6 Vladimir Kvashin 2011-01-24 07:57:25 UTC 
It's just a wrong assertion. We'll get it each time a file was deleted just after the correspondent #include was resolved (but before this file was lexed). 

In such case an exception is thrown and it is logged by caller (with WARNING level), I've just checked.

The gmoduleconf.h file is recreated when configuring or building, so it's exactly the case.
