I/O error : Memory allocation failed : growing input buffer

Hi,

We get the following error when trying to validate a 1GB DAE file with DAEValidator (@lasalvavida 's [fork](https://github.com/lasalvavida/OpenCOLLADA), built on CentOS 7.x 64 bits with a recent GCC version from [Developer Tool-set 7](https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/):

```bash
DAEValidator --check-links mesh_6M_mapped_m.dae

Processing mesh_6M_mapped_m.dae (1GB)
I/O error : Memory allocation failed : growing input buffer
Checking links...Processed 1 documents in 3.151s
Validation SUCCEEDED.
```
What are we doing wrong ? And is the validation really successful ?

P.S: the server running DAEValidator has 4 vCPUs and 8GB of RAM.

Best, Samuel from CINES

Start by reproducing the reported command, DAEValidator --check-links mesh_6M_mapped_m.dae, against the 1GB DAE file and record its output and result. Trace how the validator handles the input buffer when memory allocation fails, then determine whether validation should report failure instead of “SUCCEEDED.”
