[vtk-developers] Crashes after recent checkins

[Bill Lorensen]

My linux builds (Fedora and Ubuntu) have started crashing after recent
checkins. My MAc builds and runs fine.


The executables crash on exit. Looks like this->Internal is NULL.

For example when I run Cone,
Program received signal SIGSEGV, Segmentation fault.
0x011671b8 in vtkAtomicInt32::Increment (this=0x12b1a30)
    at
/home/lorensen/ProjectsGIT/VTKGerrit/Common/Core/Sequential/vtkAtomicInt32.cxx:49
49        this->Internal->AtomicInt32CritSec);
Missing separate debuginfos, use: debuginfo-install
python-libs-2.6.4-27.fc13.i686
(gdb) list
44
45    int vtkAtomicInt32::Increment()
46    {
47      return vtkAtomicInt32Increment(
48        &this->Internal->Value,
49        this->Internal->AtomicInt32CritSec);
50
51    }
52
53    int vtkAtomicInt32::Add(int val)
(gdb) print this
$1 = (vtkAtomicInt32 * const) 0x12b1a30
(gdb) print this->Internal
$2 = (vtkAtomicInt32Internal *) 0x0
(gdb)

Here is the traceback:
