Hi Bill,
Here is a first peek at what GDB shows for
ctest -R itkRankImageFilterTest3
---
It seem to stop at itkRankHistogram.h:279
----
Program received signal EXC_ARITHMETIC, Arithmetic exception.
0x0040deb8 in itk::Function::VectorRankHistogram<unsigned
char>::GetValueBruteForce (this=0x1d8e4f0) at itkRankHistogram.h:279
279 unsigned long target = (unsigned long)( m_Rank * ( m_Entries -
1 ) ) + 1;

I don't quite see why...
The relevant values in this line are:
(gdb) print m_Rank
$1 = 0.5
(gdb) print m_Entries
$2 = 20
(gdb) print target
$3 = 30991600
I'm wondering if I should tell gdb to stop when
that specific exceptions are thrown...
I'm taking a look at the gdb tutorial / documentation...
