Hi,
I have just learned about OIIO and I wrote a simple program with
OpenImageIO to load a 10GB PGM file into memory. To try things out I wrote
a simple program to load a 10GB PGM (yeah, PGM) file into memory. Sadly,
the program crashes prior to completing its task with a Segmentation Fault.
The machine where this is running has 64GB RAM, most of it free. Can anyone
help me figure out this issue?
Bellow is the program I wrote. It is pretty simple: load the image given as
argument to it into a buffer, then close the file, clean the buffers and
leave.
================CODE================
#include <iostream>
#include <string>
#include <sstream>
#include <OpenImageIO/imageio.h>
OIIO_NAMESPACE_USING
int main(int argc, char* args[])
{
if (argc != 2)
{
return 1;
}
const std::string filePath = args[1];
ImageInput *in = ImageInput::open (filePath);
const ImageSpec & spec = in->spec();
const int size = spec.width * spec.height;
unsigned char * pixels = new unsigned char[size];
in->read_image(TypeDesc::UCHAR, pixels);
std::cout << "Done reading." << std::endl;
in->close();
std::cout << "Closed file." << std::endl;
delete in;
delete pixels;
std::cout << "Outta here." << std::endl;
return 0;
}
================CODE================
Segfault happens at line 173 of onminput.cpp. Here is the call stack given
by Qt Builder:

I compiled OIIO from the git commit
d64b9ac8a63261040ae0263b0709924d8fecf4df (Tue Sep 3 12:53:12 2013 -0700).
I appreciate any help.
