c++ - OpenBLAS crash on Windows -


i'm working openblas on windows , experiencing crashes. i'm using test code bellow (entire program), taken intel mkl here (i modified it). same problem other function calls. step step debugging, crash occurs after return 0 in main. loop outputs matrix print correct result.

double *a, *b, *c; int m, n, k, i, j; double alpha, beta;  m = 2, k = 2, n = 2; alpha = 1.0; beta = 0.0;  = (double *) malloc(m*k*sizeof(double)); b = (double *) malloc(k*n*sizeof(double)); c = (double *) malloc(m*n*sizeof(double));  (i = 0; < (m*k); i++) a[i] = (double) (i + 1); (i = 0; < (k*n); i++) b[i] = (double) (-i - 1); (i = 0; < (m*n); i++) c[i] = (double) 0.0;   cblas_dgemm(cblasrowmajor, cblasnotrans, cblasnotrans,     m, n, k, alpha, a, k, b, n, beta, c, n);   printf("\n top left corner of matrix c: \n"); (i = 0; i<min(m, 6); i++) {     (j = 0; j<min(n, 6); j++)         printf("%12.5g", c[j + i*n]);     printf("\n"); }  free(a); free(b); free(c);

the crash occurs after exit(mainret) executed.

 #else  /* !defined (_winmain_) && defined (_crt_app) */         if ( !managedapp )         {  #ifndef _crt_app             exit(mainret);  #else             _exit_app();  #endif  /* _crt_app */  #if !defined(_winmain_) && defined(_crt_app)             /* winapi_family_app "windows" applications should never reach here,              * console applications if not exit process.              * so, terminate process console apps              */             exitprocess(mainret);  #endif         }

the first thing thought of esp value, might corrupted if function calling conventions not match (i'm using prebuilt mingw openblas 0.2.14 libraries), esp checks in debug build pass successfully. i'm using msvc++ compiler , built assembly 32-bit.

how can pinpoint problem more precisely or might cause behind crashes?

c# - Validate object ID from GET to POST -

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
