Package: gcc-snapshot
Version: 20180107-1
Severity: normal
Dear Maintainer,
I should have reported this upstream, but creating an account on GCC Bugzilla
takes a day. In the meantime...
This sample C++ program
$ cat broken.cc
struct Rect {
int width;
};
void f() {
const Rect rect = {11}; // This should be constexpr
char str[1][rect.width+1] = {
{"12345678901"},
};
}
fails compilation with this error:
$ /usr/lib/gcc-snapshot/bin/g++ -std=c++17 -c broken.cc
broken.cc: In function 'void f()':
broken.cc:9:3: internal compiler error: in process_init_constructor_array, at
cp/typeck2.c:1318
};
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-snapshot/README.Bugs> for instructions.
If I've understood the standard correctly, the expression used as the size of
the array should be a constexpr, and the compiler should complain about it.
Asking the user to file a bug report instead of fixing their code is the wrong
response.
