Unhandled exception

fanhanqi — Fri, 13 Oct 2006 14:32:20 GMT

I use MKL8.01 in VS2005, and code below:

bool linsol ( int n, float *a, float *b )
{
	int nrhs = 1;
	int *ipiv = new int ;
	int info = 0;
	/* -------------------------- */
	//float a[16] = { 1, 0, 0, 0,
	//		  0, 1, 0, 0,
	//		  0, 0, 1, 0,
	//		  0, 0, 0, 1
	//       	    };
	//float b[4] = {1, 1, 1, 1};
	//int n = 4;	
	/*-------------------------------*/
	sgetrs( "T", &n, &nrhs, a, &n, ipiv, b, &n, &info );
	if (info == 0)
		return true;
	return false;
}

The commented lines are the data values.


When I call this function, there is 
"Unhandled exception at 0x00451952 in Hermite.exe: 0xC0000005: 
 Access violation reading location 0x374a2b88."

And I found that the CallStack show the problem as below:

 	Hermite.exe!_mkl_blas_p4p_sswap()  + 0xe2 bytes	Asm
 	Hermite.exe!_mkl_lapack_sgetrs()  + 0x25e bytes	
 	Hermite.exe!_mkl_blas_sswap()  + 0x93 bytes	
 	Hermite.exe!_mkl_lapack_slaswp()  + 0x18c bytes	
 	0012f470()	
>	Hermite.exe!CHermiteDlg::Hermit()  Line 226	C++
 	

However, I don't know how to solve it. 
Is there anyone can help me?
Thanks.
