Summary: [7 Regression] ICE on some fortran code with -flto
-Ofast
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: GC, ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Take the following fortran 90 code:
MODULE Errorcheck_mod
CONTAINS
SUBROUTINE Check_open(ios, outputstr, errortype)
character(len=*), intent(in) :: outputstr
if (ios > 0 .AND. errortype == FATAL) then
write(*,*) 'The value of ios was:', ios
end if
END SUBROUTINE Check_open
END MODULE Errorcheck_mod
---- CUT ----
Compile it like:
gfortran -nostdlib -r -Ofast -flto --param ggc-min-expand=0 --param
ggc-min-heapsize=0 errorcheck.f90
You get the following ICE:
lto1: internal compiler error: in ipa_get_type, at ipa-prop.h:448
