Bug ID: 107215
Summary: ICE in gfc_real2real and gfc_complex2complex
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Additional examples affect versions down to at least r5 :
$ cat z1.f90
program p
double precision, parameter :: z = 1.0d0
real :: y(1)
complex :: x(1)
x = [real :: -'1'] * z
y = z * [real :: -'1']
x = [real :: -(.true.)] * z
y = z * [real :: -(.true.)]
end
$ cat z2.f90
program p
double precision, parameter :: z = 1.0d0
real :: y(1)
complex :: x(1)
x = [complex :: -'1'] * z
y = z * [complex :: -'1']
x = [complex :: -(.true.)] * z
y = z * [complex :: -(.true.)]
end
