[REG 7.0 -> 8.0] CMakeProjectManager crashes when configuring fails

If I open a CMakeLists.txt-based project which fails to configure (due to any kind of error), Qt Creator crashes.

CMakeProcess::lastExitCode() is called on a 0-pointer. Usage after destruction?

The inferior stopped because it triggered an exception.
Stopped in thread 0 by: Exception at 0x7ff81b13877b, code: 0xc0000005: read access violation at: 0x58, flags=0x0 (first chance).
