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: unassig...@gcc.gnu.org
ReportedBy: juno.kr...@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.
