Description Andrew Pinski 2005-07-14 13:46:29 UTC 
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.
Comment 1 Andrew Pinski 2005-07-14 13:49:17 UTC 
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];
}
Comment 2 Andrew Pinski 2005-07-14 18:31:45 UTC 
Another testcase:
struct QRgbMap {
  QRgbMap();
};
void convert_32_to_8() {
  QRgbMap table[10];
}
Comment 3 Andrew Pinski 2005-08-05 05:13:11 UTC 
Confirmed:
t.cc:14: error: types mismatch in comparsion
long intD.5
intD.2
D.1753 != -1;
Comment 4 Andrew Pinski 2005-10-09 20:47:16 UTC 
Even further reduced testcase:
struct _Words     {_Words();};
_Words _M_local_word[2];

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