[Bug middle-end/19084] New: ICE: internal consistency failure

[aj at gcc dot gnu dot org]

Compiling glibc with "gcc -m32" on Linux/AMD64 gives me the following
ICE with current GCC CVS:

Hmm, this works for me with a cross to x86_64 from darwin compiled at -O0.

[Bug middle-end/19084] [4.0 Regression] ICE: internal consistency failure

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-01-09 18:53 -------
Confirmed, I don't know if this is a regression or not but I am going to assume so as I could not 
reproduce this before.
Reduced testcase:
unsigned long long
__lcong48_r (unsigned short param)
{
  return ((unsigned long long) param << 32);
}
