 Description   

Started happening recently. Maybe it's related to sid upgrade (gcc 6 and such).

Failed to repeat this on both my laptop or perro (used --repeat=60 --parallel=4 few times). Need a stack trace if fails again.

It only happens on sid.
Maybe cvicentiu knows something about it? (in case it's related to gcc 6).

Comment by Vicențiu Ciorbaru [ 2016-09-30 ]

The only thing that I know for certain about gcc 6 is that they always assume "this" pointer is not null. Any if conditions that check for this are automatically set to true.

We previously had something like:

bool SomeClass::method() {
 
     if (!this) return true;
 
     return false;
 
}
 
 
 
SomeClass *p = NULL;
 
p->method();  // Before GCC v6 this returned true all the time. Now it returns false all the time.

There are some places in the code where we do this. I plan to fix them, but strapped for time till the dev meeting.

10.1 is EOL.
