…Use Safari! (lol,)
Google Chrome 39 had started to crash for me as soon as I updated to 10.10.2 Beta. I tried all of the normal things (trashing Google prefs, using Canary, etc etc). Nothing worked except downgrading back to Mac OS 10.10.1 stable.

It turns out that the new 10.10.2 has depreciated some Trackpad APIs that cause an immediate crash.
The answer comes via Reddit today:

Obviously use at your own risk: an Automator app has also been built to speed up the below process.
Workaround that was found on the Apple dev forums – this is not my code – use at your own risk – I’ve used it and it works fine.
1) Open up text edit and paste this code – save it as “patch.m”
#import <AppKit/AppKit.h>
__attribute((constructor)) void Patch_10_10_2_entry()
{
NSLog(@"10.10.2 patch loaded");
}
@interface NSTouch ()
- (id)_initWithPreviousTouch:(NSTouch *)touch newPhase:(NSTouchPhase)phase position:(CGPoint)position isResting:(BOOL)isResting force:(double)force;
@end
@implementation NSTouch (Patch_10_10_2)
- (id)_initWithPreviousTouch:(NSTouch *)touch newPhase:(NSTouchPhase)phase position:(CGPoint)position isResting:(BOOL)isResting
{
return [self _initWithPreviousTouch:touch newPhase:phase position:position isResting:isResting force:0];
}
@end
2) Run this command in Terminal
clang -dynamiclib -framework AppKit ~/Desktop/patch.m -o ~/Desktop/patch.dylib
3) Run this command in Terminal to open Chrome.
env DYLD_INSERT_LIBRARIES=~/Desktop/patch.dylib "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
Notes: This will leave Terminal open in the background, do not close it or Chrome will quit out. This doesn’t modify anything permanently just fixes it temporarily. To reopen chrome a second time all you have to do is repeat step 3.
