Bug ID: 93777
Summary: ICE in maybe_cast_1, at analyzer/region-model.cc:5064
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
gfortran-10.0.1-alpha20200216 snapshot
(g:6e37e49616d429c5d922324ebd72ae95f12a079f) ICEs when compiling the following
testcase, reduced from gcc/testsuite/gfortran.dg/block_13.f08, w/ -fanalyzer:
program cb
implicit none
type :: jn
real, allocatable :: ie
character(len = :), allocatable :: e5
end type jn
real, parameter :: gm = 5.0
block
type(jn) :: r2
r2 = jn (gm, "")
call vz (r2%ie, gm)
end block
contains
subroutine vz (arg1, arg2)
real :: arg1, arg2
if (arg1 .ne. arg2) STOP 1
end subroutine vz
end program cb
