This symptom does exist since eternity already. At least since ros 0.4.7, but I think it was the same already around 0.4.2 or so.
The MSVC 2010 debug builds do run fine. BootCD up to third stage desktop. LiveCD to desktop.
But the MSVC 2010 release builds do both crash with BSOD0x7F.
In the past I always observed the reproducible BSOD 0x7F only for bootcd in 2nd stage, and did not know how to grab any logs.
But today I realized, that if I use the LiveCD and select "Debug" from bootmenu, I can even grab some logs for that (with putty even!). And I even got kind of a callstack.
Since the callstack can not be translated, I instead attached the 2 binaries as well:
To build such a LiveCD use
As said, the bootcd fails with the same BSOD, but only in 2nd stage. The 1st stage already runs fine with that.
