I would check your compiler and make sure you're using the newest
version of m5.
test.c:
#include <stdio.h>
int main( void )
{
double a[2];
a[0] = 2.3;
a[1] = 5.7;
printf( "a[0] = %f\n", a[0] );
return 0;
}

That is very odd. Does the fault also occur if you put a[0] into a
temporary variable before sending it to printf? What compiler/library
are you using?

hi,
I found why the error of "panic: Page table fault when accessing
virtual
address 0" will occur.
See the following program:
int main( void )
{
double a[2];
a[0] = 2.3;
a[1] = 5.7;
printf( "a[0] = %f\n", a[0] );
}
When you define an array of float point and you print the
element of the
array with printf ,then the fault will occur.
But i don't know why?
Thank you!
