 Description   

We're writing a custom app that uses an XWalkView. All the app does is load a URL in the XWalkView. We're primarily driving WebGL and JS intensive examples for testing.

Usually we get the segfault after running for a few minutes, but sometimes it happens pretty much instantly when the application is first launched.

Here's the stacktrace. It's the only information I have to go on at this point. If you know of any other ways for me to pull debug info please let me know and I will add that data here.

It's possible that this is not directly related the crosswalk, but I'm under the impression that it is as this doesn't seem to happen outside of this sample application we've created.

EDIT: I added a second stack trace from a different crash where it had a FBADBEEF

Stacktrace below:
(note, sometimes we get DEADBAAD when it dies, other times we get FBADBEEF

It might be memory crash (e.g. use-after-free) because it crashes in libc.so
It might be duplicated to XWALK-1778

Comment by A. Ross Cohen (Inactive) [ 16/Jun/14 ]

It could be related but I have a feeling it's not, at least not directly. The segfaults that show up in the logs for XWALK-1778 are all at 0x00000000 which to me looks like a null pointer deref, whereas the issue I'm having has always crashed with either 0xfbadbeef or 0xdeadbaad. Also, the stack traces often point back to __pthread_clone or __pthread_create (which makes sense as it would be allocating memory for that, right?)

I'm currently re-building my Android distro from src with a different version of the Vivante GPU drivers, which did have a known memory allocation issue in some versions. I'll keep you posted on wether or not it has any effect.

Comment by Balestrieri, Francesco [ 26/Jun/14 ]

A. Ross Cohen did the rebuild help?

Comment by A. Ross Cohen (Inactive) [ 26/Jun/14 ]

Unfortunately it didn't make a difference. I don't have any new clues as to what the issue is, but I do know that it seems to be specific to the wandboard BSP. I run an almost identical build on a different board (nitrogen6x from boundary devices) and I haven't seen it segfault yet.

Comment by sqliu (Inactive) [ 01/Jul/14 ]

As this issue can only be reproduced in the specific device (wandboard BSP). So I think we can lower the priority of this bug (P2).

Comment by tinazhao (Inactive) [ 02/Jul/14 ]

This issue has been discussed and agreed to move to P2.

Assign to sun lin, and please help to redistribute the bugs.

A. Ross Cohen Could you help to verify it with the latest Crosswalk-14 on Wandboard? Thanks.
