Bug #: 53586
Summary: Internal compiler errors on cp/pt.c:12077 and
expr.c:9147
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: paulotorrens@gnu.org
Trying to compile this small function:
template<typename T> auto ptr2bitmap(T *bitmap, int width, int depth = 3) ->
typeof(typeof(unsigned char[depth])[width]) *{
return bitmap;
};
I got this:
Compiling `mjpeg.cpp'...
mjpeg.cpp: In substitution of 'template<class T> unsigned char (*
ptr2bitmap(T*, int, int))[width][depth] [with T = void]':
mjpeg.cpp:223:39: required from here
mjpeg.cpp:200:27: internal compiler error: in tsubst_copy, at cp/pt.c:12077
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://trac.macports.org/newticket> for instructions.
make: *** [mjpeg.o] Error 1
And, trying to compile this code:
using uc3 = unsigned char[3];
using uc3w = uc3[width];
using uc3wp = uc3w *;
auto img = (uc3wp)rgb;
int w = 0;
for(w = 0; w < font_GMT_width; w++) {
for(int y = 0; y < font_height; y++) {
((img[y])[w])[0] = font_pixel(font_GMTX + w, y, 0);
((img[y])[w])[1] = font_pixel(font_GMTX + w, y, 1);
((img[y])[w])[2] = font_pixel(font_GMTX + w, y, 2);
};
};
auto add = [&](int start) {
for(int x = 0; x < font_char_width; x++, w++) {
for(int y = 0; y < font_height; y++) {
((img[y])[w + x])[0] = font_pixel(start + x, y, 0);
((img[y])[w + x])[1] = font_pixel(start + x, y, 1);
((img[y])[w + x])[2] = font_pixel(start + x, y, 2);
};
};
};
auto add_colon = [&] {
add(font_ColonX);
};
auto add_slash = [&] {
add(font_SlashX);
};
I got this:
mjpeg.cpp: In static member function 'static void
std::_Function_handler<void(_ArgTypes ...), _Functor>::_M_invoke(const
std::_Any_data&, _ArgTypes ...) [with _Functor = MJPEG::Video::addJpg(void*,

What happens if you use decltype instead of typeof ?

(In reply to comment #1)
> What happens if you use decltype instead of typeof ?
template<typename T> auto ptr2bitmap(T *bitmap, int width, int depth = 3) ->
decltype(decltype(unsigned char[depth])[width]) *{
return bitmap;
};
int main() {
void *x;
auto a = ptr2bitmap(x, 100);
};
test.cpp:2:10: error: expected primary-expression before 'decltype'
test.cpp:2:10: error: expected ')' before 'decltype'
test.cpp:2:1: error: expected type-specifier before 'decltype'
test.cpp:2:1: error: expected initializer before 'decltype'
And without decltype and typeof at all:
template<typename T> auto ptr2bitmap(T *bitmap, int width, int depth = 3) ->
unsigned char[depth][width] *{
return bitmap;
};
int main() {
void *x;
auto a = ptr2bitmap(x, 100);
};
test.cpp:2:15: error: use of parameter 'depth' outside function body
test.cpp:2:22: error: use of parameter 'width' outside function body
test.cpp:2:29: error: expected initializer before '*' token
