The Cool VL Viewer should never open the crash reporter unless you manually changed the crash reporting setting (it makes no sense for a TPV to send debug info to Linden Lab, since they don't provide any support for TPVs...), but the new packaging method indeed provides a crash reporter that could be used, unlike Snowglobe's.
Nevermind SecondLife.dmp is enough for me to see where things happened. Apparently, this is again a Multi-threaded curl issue (although the viewer uses the "fixed" code that LL uses in their newest viewers). "Congrats" !.... You are the first person to report such an issue since the new multi-threaded curl code was adopted...
Anyway, and until some truly fixed code is released by LL, simply go to the "Advanced" menu (type CTRL ALT D if it doesn't show in the menu bar), "Network" sub-menu, then un-check the "Multi-Threaded Curl" and restart the viewer. You should not encounter such crashes after that (but you might get a short "hiccup" in the frame rate each time a new curl request is done).
It could be interesting as well to test LL's latest viewer and see if you get the same crash with Multi-threaded curl active, in which case you could open a JIRA issue for LL's viewer: that would help getting a fix faster, because I develop and use the viewer under Linux and never see this kind of crash happening here (and I can't track down a bug I can't reproduce)...
