Description Ulrich Weigand 2002-10-15 10:16:01 UTC 
ICE when building the TeX package on s390x-ibm-linux
in dviconcat.c:

Internal compiler error in emit_move_insn, at expr.c:2769

Release:
gcc 3.2

How-To-Repeat:
This code snippet reproduces the ICE:

int f (char *p, char *q, int i)
{
  return bcmp (p, q, i);
}
