I've tried both, the unofficial Gentoo ebuild of Android Studio from the mrueg overlay (android-studio-130.687321.ebuild) as well as the bundled package from http://developer.android.com/sdk/installing/studio.html (android-studio-bundle-130.737825-linux.tgz).
While both install fine and let me run Android Studio itself without any problems, adb (and also the fastboot utility) give me a segmentation fault, no matter if i start it with or without any arguments / parameters (such as "adb version").
I've tried deleting and reinstalling the platform-tools from within the Android-SDK-update-manager, but that also didn't help.
I've tried gdb, but to no avail since adb was built without debug symbols.
I'm running an up to date Gentoo ~amd64 and have used revdep-rebuild to make sure my system is consistent.
Any pointers welcome...
