2009-01-21 Thread domob at gcc dot gnu dot org 


--- Comment #5 from domob at gcc dot gnu dot org  2009-01-21 13:37 ---
Fixed on trunk by converting the abort() call in internal_unpack to a return
(this is also what the real unpack library call does).

Created an attachment (id=17130)
 -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17130action=view)
Difference of the dump

The problem is the call
_gfortran_internal_unpack (parm.2, D.1572);
since the array has zero extent. The _gfortrani_internal_unpack_4 has the
following check:

61extent[n] = d-dim[n].ubound + 1 - d-dim[n].lbound;
62if (extent[n] = 0)
63  abort ();

Daniel, you worked on MVBITS for PR 35681 (Rev. 141516). Could you have a look
for this PR and also PR 38883. Thanks!
