Compiler Warning (level 4) C4764
Visual Studio 2005
Error Message
Cannot align catch objects to greater than 16 bytesAn alignment greater than 16 was specified, but on some platforms, if the function throws an exception, the stack will force an alignment of not greater than 16.
Example
The following sample generates C4764:
// C4764.cpp
// compile with: /W4 /EHsc
// processor: x64 IPF
#include <stdio.h>
class A
{
public:
int x;
};
typedef __declspec(align(32)) A ALIGNEDA;
int main()
{
ALIGNEDA a;
try
{
a.x = 15;
throw a;
}
catch (ALIGNEDA b) // can’t align b to > 16 bytes
{
printf_s("%d\n", b.x);
}
} // C4764
