I then tried running chromium with the --disable-sync command line option, which causes chromium to start normally and not crash (although, obviously, sync no longer works). I also tried moving my ~/.config/chromium directory and restarting Chrome. Chrome started successfully, and I was able to sign into my account. However, when I input my sync password (I use encrypted sync), the segfault reappears immediately after. As a point of comparison, I also installed www-client/google-chrome-unstable-35.0.1862.2_p1. I can sign in and use sync successfully in google-chrome-unstable with no crash. Note that the version number is the same between chromium and google-chrome-unstable. Chrome sync was working without a hitch in chromium until today. Reproducible: Always Steps to Reproduce: 1. Launch chromium. 2. Sign into Chrome sync. Actual Results: Segmentation fault occurs. Expected Results: Chrome sync works without crashing.

I had the same problem with 34.0.1847.14 and 35.0.1862.2, returning back to 33.0.1750.117 fixed that for me.
I can confirm this.
Using the bundled protobuf library seems to resolve this in chromium-35.0.1862.2. I am going to perform the same test in chromium-34.0.1847.14, and will commit it if successful. phajdan.jr: Do you want to switch to bundled protobuf in chromium-35, or do you want to try and debug the issue with system protobuf?

(In reply to Mike Gilbert from comment #3) > phajdan.jr: Do you want to switch to bundled protobuf in chromium-35, or do > you want to try and debug the issue with system protobuf? I was thinking about debugging, but I can do that with a modified ebuild. Feel free to change 35. I'll probably either do it myself and/or debug. Thanks for addressing this quickly, that's obviously good for everyone. :)
