Ah! Here's a bit more concise test case, which write only 1 integer:

#include <matio.h>

int main()
{
	mat_t * mat = Mat_Open( "foo.mat", 0 );
	if ( mat==NULL ) abort();

	int dims[2] = {1,1};
	int i = 42;

	matvar_t * matvar = Mat_VarCreate( "test", MAT_C_INT16, MAT_T_INT16,
			2, dims, &i, 0 );

#if 1
	/* writes broken file */
	Mat_VarWrite( mat, matvar, COMPRESSION_ZLIB );
#else
	/* writes working file */
	Mat_VarWrite( mat, matvar, 0 );
#endif

	Mat_Close( mat );

	return 0;
}

Attached are the output file from this program (foo.mat) and the fiel as
matlab itself saves it, generated by:
  > load('foo.mat');
  > save('foo_matlab.mat','test') 
in Matlab 2009b.
Note that the file are 1 byte different in length.

Hope this helps!

Kind regards,
Bas.
