Guild Wars 2

I have the same problem with my Imac. It happens during events, especially in the Silverwastes. It’s so bad atm that I don’t want to play anymore, because every time I’m doing an event, the client crashes. The error codes I get are Tcmalloc, c000005, success, lockedrect.pbits and sometimes it just quits without error code. Any help or advice would be appreciated!

My Imac:
processor: 3.1 GHz intel i5
memory: 20 GB
graphics: AMD radeon HD 6970M 1024MB

I have the same problem, since the Wintersday update, my client crashes every 10 mins or so. I never had any problems before on my mac. So I can’t play anymore till this is fixed.
