Crash during resourcType is RT_XHR(XMLHTTPRequest)

[Yubtest]

Hi,

Trying to load a url and there are some XMLHTTPRequests going out which I can see from GetResouceType() API. During this I get a crash. Crash wont happen If I do a RT_CANCEL from OnBeforeResourceLoad when resourceType is RT_XHR,

Video/Audio getting downloaded was auto playing and i have set 'user-gesture-required' from command line and tried SetAudioMuted , but I couldn't solve the issue. Can some one please suggest a way to fix the issue

please find the back trace during the crash

Appreciate any help

Thanks

What OS and CEF version? What reproduction steps? Does the crash reproduce in the CEF sample apps?

[Yubtest]

Hi,'

I have used cef_binary_80.1.14+ga33bdbc+chromium-80.0.3987.149_linux64_minimal.tar.bz2 and using ubuntu Machine.

I dint check in sample. Will let you know once I test with sample application

Thanks

[Yubtest]

I have checked with cefclient sample and it does not have any issues.

URL which I am using is of an internal site which cant be accessible out side.


Thanks

[Yubtest]

I have an update, was using --single-process command line and it was creating the issue. No issues when i have removed it.


Now, I need to create a separate subprocess. i have seen https://bitbucket.org/chromiumembedded/ ... executable and it seems it is for Mac, i wnt be able to use the same process for all the process as i am creating browser window from another gtk window

Can you please suggest what should be the format in Linux to create a seperate subprocess executable.

Thanks

I have another crash during application exit. This is happening after cefShutdown and while application exit

Can Someone help me on this?
