I make some other trials and it seems that the origin of the crash of Arma3 is the presence of Ts3overlay plugin files in Teamspeak.
So, as soon as Teamspeak was launched before or after Arma3, I got a crash of Arma.
After many trials I discover that the plugin TS3overlay was involved in the problem. So,I suppress TS3overlay plugin and reinstall Teamspeak. Since this modification I don't have any problem with the launch of Arma.

I suppose that you speak about the .rpt that I find in User/Appdata/local/Arma3.
I make a zip with all of them.
Today, I discover that my Arma3 crash when I launch Teamspeak with the new plugin TFAR.

I make the try without any mods. But the result was the same.
The report has been join.ArmaReport_Log_20150827T183755.zip

Thanks for your advice Krisstal. You're right. The problem has been solved as soon as I have disabled the "streamfriendly UI".
I suppose that I have enabled it accidentaly too.

Not a bogue.
