1294712 - Content process crashes when trying to load a large profile from SPS profiler

Status: RESOLVED DUPLICATE of bug 1761578

(Core :: Gecko Profiler, defect)

Description

[Katelyn Gadd (:kael)]

If I turn on Main Thread I/O and GPU profiling, trying to analyze after profiling a page for a few moments crashes the content process with bug 1271102 as the stack. It's was consistently reproducible until I restarted my session, but it's not reproducing right now. I'll see if I can get it to happen again.

Here are the content process crashes:

Looks like your profiler data is too large. The crash is in mozilla::dom::ContentChild::RecvGatherProfile() and mozilla::dom::PContentChild::SendProfile(nsCString const&)

Although we might lift the limits in bug 1271102 we should still try to avoid these kind of large allocation.

Marking this old bug as duplicate of bug 1761578, as the newer one has more recent information.
