[Insight-users] Segmentation fault with 2.2G data but not with smaller subset

[lynx.abraxas at freenet.de]

Hello!



My  little SignedDanielssonDistanceMapImageFilter and watershed filter program
runs fine with a subset (45M) of my acutal data but when I use the  full  data
set  (2.2G)  it  stops after a minute with a segmentation fault. What could be
the cause for that? Below is  some  gdb  output  I'm  not  able  to  interpret
further.

Thanks for any help or hints
