------- Comment #11 from janus at gcc dot gnu dot org 2009-10-20 20:15 -------
Ok, I have identified the place in libgfortran where the segfault happens:
#0 *_gfortran_pack (ret=0x7fffec3ca650, array=0x7fffec3ca620,
mask=0x7fffec3ca440, vector=0x0) at
/home/jweil/gcc45/trunk/libgfortran/intrinsics/pack_generic.c:364
That line is:
if (GFC_UNALIGNED_4(ret->data) || GFC_UNALIGNED_4(array->data)
|| GFC_UNALIGNED_4(vector->data))
break;
So, the problem is that we ask for the 'data' field in the optional VECTOR
argument, which is not present here (i.e. vector=0x0)!
