Very very bad :). 

VC++ is very good in C++ exceptions code optimization. Typically - 
exception code is moved away from function body.

Sample functions:

void TestFuncA()
{
    try
    {
        printf( "aaaa" );
    }
    catch(...)
    {
        exit(-1);
    }
}

void TestFuncB()
{
    printf( "aaaa" );
}

----------------

VC++2k5 asm output(  no differences):

PUBLIC    ?TestFuncA@@YAXXZ                ; TestFuncA
_TEXT    SEGMENT
?TestFuncA@@YAXXZ PROC                    ; TestFuncA
    push    OFFSET ??_C at _04CLOGDNII@aaaa?$AA@
    call    DWORD PTR __imp__printf
    pop    ecx
    ret    0
?TestFuncA@@YAXXZ ENDP                    ; TestFuncA
_TEXT    ENDS


PUBLIC    ?TestFuncB@@YAXXZ                ; TestFuncB
_TEXT    SEGMENT
?TestFuncB@@YAXXZ PROC                    ; TestFuncB
    push    OFFSET ??_C at _04CLOGDNII@aaaa?$AA@
    call    DWORD PTR __imp__printf
    pop    ecx
    ret    0
?TestFuncB@@YAXXZ ENDP                    ; TestFuncB
_TEXT    ENDS
