Memory allocation crash in idc.exe

This is actually two separate bugs, the first is using uninitialized memory, the second, is using an unchecked invalid value via implicit conversion.

qaxserver.cpp:1127 uses an unallocated variable, on my machine, this gets set to -1, which gets passed down through the stack to QCoreApplicationPrivate (qcoreapplicationprivate:287), which then tries to allocate this value converted to uint, which leads to a crash in windows.

Address 0x0019ee68 points into a thread's stack
