Started to frequently crash (since 1.1.2) here as well. With and without mods. Either after deploying parachutes or solar cell arrays, or just while in the SPH or on the launchpad. Up comes a small window with an access violation ("Write to location 400d2a48 caused an access violation."), sometimes I get a crash report ("KSP_x64.exe caused an Access Violation (0xc0000005) in module KSP_x64.exe at 0033:3ff3db12"). Thanks for all the work.
Edit: Looks like Calvin Maclure`s.
