Bug #: 55345
Summary: ICE with abstract interface type with use-renamed
local names
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: juno.krahn@nih.gov
If an abstract interface type is renamed in the USE statement, and one of those
names includes the original name, an ICE can occur.
Example code (bug.f90):
----------------------------------
module mod1
abstract interface
subroutine func_t()
end subroutine func_t
end interface
end module mod1
module bug
use mod1, func_t=>func_t, func1_t=>func_t
end module bug
----------------------------------
Result:
$ gfortran -c bug2.f90
bug.f90:8:0: internal compiler error: in gfc_trans_use_stmts, at
fortran/trans-decl.c:3886
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
If the two USE statements are switched, no ICE occurs. It also succeeds if the
rename statements are within an ONLY list.

Confirmed for 4.6.3. The ICE has been fixed for 4.7 between revisions 183001
(2012-01-09, ICE) and 183091 (2012-01-11, OK). Revision 183010 seems a good
candidate for the fix. The last comment for pr51578 says:
> FIXED on the trunk (GCC 4.7). Too big for backporting [esp. as no one has
> reported the bug/regression for years].
So please update your gfortran to 4.7.2.

Abstract interfaces and rename aliasing are both seldom used, plus there is a
work-around, so I agree that there is no need for back porting.
