[Insight-users] ITK memory allocation exception question

[Miller, James V (Research)]

Robert, 

What OS are trying to run on?

A stock Windows configuration only allows a process to access approximately
1GB of memory.  A stock linux configuration allows a process to access
approximately 3GB or memory.

That being said, it looks like a bad error message from the MetaImage.
It looks like the size is being converted from an unsigned to a signed
quantity.

Jim

Subject: [Insight-users] ITK memory allocation exception question


Hi everyone,

I have an C++ program using ITK that tries to write a
1222x1754x256 floating point volume to memory but
gives the following exception instead:

MetaImage: M_ReadElements: data not read completely
   ideal = -2100137984 : actual = 0

followed later in the algorithm by:

terminate called after throwing an instance of
'std::bad_alloc'
  what():  St9bad_alloc
Aborted

There is a total of 32GB of memory on the machine, and
the total amount of memory used by the volume should
be approximately 2 GB.

Can anyone tell me why this exception is usually
thrown?

Thanks,

Robert
