Dear all,
I would like to post a fault report for the GNU C/C++ compiler 3.3-e500.
We use the compiler to generate code for a PowerPC processor.
Used invokation line for the GNU C++ compiler:
ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
-fmerge-templates -mmultiple -mno-string -mstrict-align -O3
-fno-exceptions -fno-rtti -fno-builtin-printf
-I<different include paths>
-D<differen #define's>
K.CPP -oK.O
// example program
void f1 (int*);
void f2 (int**);
void f3 ()
{
f1 (new (int*)[3]); // legal
f2 (new (int*)[3]); // illegal
}
I get the error message "cannot convert `int**' to `int*' for argument `1'
to `void f1(int*)'".
I think this is unjustified since the expression 'new (int*)[n]' should be
parsed as '(new (int*))[n]' and not as 'new int*[n]' as the GNU compiler
seems to do: according to the standard 5.3.4 the above '(int*)' in the new-
expression should be recognized as '( type-id )'.
Therefore the compiler should accept the call of f1() and refuse the call
of f2().
With kind regards
W. Roehrl
