[Bug c++/22487] New: C++ front-end produces mis-match types in EQ_EXPR (array constructor)

[pinskia at gcc dot gnu dot org]

Testcase only in 64bit mode where sizeof (long) != sizeof(int):
struct c
{
  int t;
  int y;
  c();
};
template <typename T>
T *
allocbuf (unsigned long size)
{
  return new T[size];
}
c * a = allocbuf<c>(10);


See PR 22368 for the patch to detect this.

Oh, this has nothing to do with templates at all, reduced further:
struct c
{
  int t;
  int y;
  c();
};
c *
allocbuf (unsigned long size)
{
  return new c[size];
}

Another testcase:
struct QRgbMap {
  QRgbMap();
};
void convert_32_to_8() {
  QRgbMap table[10];
}

Even further reduced testcase:
struct _Words     {_Words();};
_Words _M_local_word[2];

This shows up while bootstrapping on x86_64-pc-linux-gnu.
