------- Comment #2 from pinskia at gcc dot gnu dot org 2006-12-13 04:40 -------
And here is a testcase which makes this a regression:
struct aaa
{
aaa(_Complex float __z) ;
_Complex float _M_value;
};
aaa::aaa(_Complex float __z)
{
__z*=2.0f;
_M_value = __z;
}
---------------------
The invalid gimple causes an ICE:
[EMAIL PROTECTED] ~]$ ~/gcc-4.1//bin/gcc -O2 t.cc -fdump-tree-all
t.cc: In constructor aaa::aaa(float __complex__):
t.cc:6: internal compiler error: in find_lattice_value, at tree-complex.c:133
Please submit a full bug report,
