Dear all,
I would like to post a fault report for the GNU C/C++ compiler 4.3.0.
Used invokation line for the GNU C++ compiler:
gcc -c -x c++ -ansi -Wall -Werror -mcpu=603e -fverbose-asm -mbig
-mmultiple -mstring -mstrict-align -meabi -msdata -fno-common
-fno-exceptions -fno-rtti -O3 -fno-section-anchors
-I<different include paths>
-D<different #define's>
X.CPP -oX.O
// example program
template <typename T_>
bool f (T_* p);
bool g ()
{ return f(static_cast<int(*)[]>(0)); }
GNU accepts the code frgment above which is illegal. It is illegal because
a function parameter like "int(*)[]" is illegal (8.3.5/6).
BTW, the Comeau online compiler rejects the code above.
Kind regards
W. Roehrl
