[Flightgear-devel] Latest CVS Crashes

[Jonathan Polley]

I just updated from CVS for both the Mac and Windows and got the same error when I tried to run. The Mac traceback is as follows:



Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000006

Thread 0 Crashed:

The error was in the same routine, so I am assuming that there is something uninitialized somewhere. The bad pointer was in slightly different lines of code, though:

if ( ovState != NULL )
ovState -> force () ; <--- Windows Crashes
else
basicState -> force () ; <--- Mac Crashes

Windows died where it did because ovState contained the Windows non-zero invalid pointer value (0xcacacaca).
