Bug ID: 121728
Summary: [PDT] Testcase gfortran.dg/pr95090.f90 ICEs under
valgrind
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: anlauf at gcc dot gnu.org
Target Milestone: ---
As I did see gfortran.dg/pr95090.f90 failing on some targets, I did run
f951 on it under valgrind and reduced it to the following:
module m
type t(n)
integer, len :: n = 8
end type
contains
subroutine s
type(t(n)) :: z
end
end
Without valgrind, it succeeds and creates a module file "m.mod", but running
under valgrind it ICEs and creates an empty file "m.mod0" and gives the
following traceback here (valgrind portions elided):
f951: internal compiler error: write_symbol(): bad module symbol 'n'
