[Insight-developers] JPEG2000 segfault and warnings

[Gaëtan Lehmann]

Hi,

Those warnings, on SunOS

"/export/home/glehmann/src/tests/ITK/Utilities/openjpeg/jp2.h", line  
80: warning: enumerator value overflows INT_MAX (2147483647)
"/export/home/glehmann/src/tests/ITK/Utilities/openjpeg/jp2.h", line  
87: warning: enumerator value overflows INT_MAX (2147483647)

can be fixed by replacing the (too large) value 0x80000000 by  
0x40000000 in the enums at the lines 80 and 87

   JP2_STATE_UNKNOWN    = 0x40000000
   JP2_IMG_STATE_UNKNOWN    = 0x40000000

Another option is to not use an enum to store those values.
I don't know which one is the best.

But this doesn't fix the segfault, unfortunately. Here is the  
backtrace I get for the test itkJPEG2000Test00:

But I really don't know what to do with that, as I don't know openjpeg  
at all...
