I got the same issue.Firing pistols, submachine guns,guns with a silencer or throwing smoke grenades won't crash it,HE grenades or unsilenced guns will.-nosound parameter "fixes" the crashing, but playing without sound can't be the final solution.validating the files via steam and replacing the arma3.exe by deleting it and the validate via steam did not fix it.Uploaded dumpfile as ArmaReport_C_Brennigan.zip.

Seems to be completely fixed with the newest update :D
