Bug 95727 – REGRESSION(near r127050): inspector tests crash intermittently in debug mode (GC related bug)

• Status: RESOLVED
• Resolution: INVALID
• Component: New Bugs

[Csaba Osztrogonác]

near r127050 inspector tests started to crash intermittently in debug mode on 32/64 bit too.
I don't know the exact revision, because Qt port wasn't buildable between r127026-r127030
and r127063-r127096. And it is a flakey crash which isn't reproducible easily ...

Some crash log:

[Csaba Osztrogonác]

It must be a GC related bug again ... crash logs contain "ZN3JSC4Heap17collectAllGarbageEv+0x2f" calls.

[Geoffrey Garen]

Can you add symbols to these crashes?

> Can you add symbols to these crashes?

Sure. I built r127452 and then generated symbols with addr2line 
for the latest crash log and ran c++filt to get demangled names.
I think we should make the buildbot to do it automatically somehow.

I think it isn't a Qt specific bug, there are GC releated 
inspector crahes on Mac Lion bot too:

It is still valid. Isn't there anybody interested in fixing these crashes?

> It is still valid. Isn't there anybody interested in fixing these crashes?

Yes, we are.  Intermittent crashes like this can be really tough to track down.  Even triaging down to a revision is often little help, since that revision often just creates the circumstances necessary to reveal a deeper bug that as been in the system for longer.  But we are investigating this, and I appreciate the investigation that you've posted on this bug so far - it's very helpful!

Closing for now, as most affected tests are removed. Please re-open if still an issue.
