Summary|internal compiler error: in |[5 Regression] ICE in
|fold_convert_loc, at |fold_convert_loc, at
|fold-const.c:2353 |fold-const.c:2353
--- Comment #3 from janus at gcc dot gnu.org ---
Here is a reduction of the original test case which gives the ICE with trunk,
but compiles cleanly with 4.9:
type :: Test
end type
type :: TestReference
class(Test), allocatable :: test
end type
type(TestReference) :: testList
testList = TestReference(Test()) ! ICE in fold_convert_loc
end
The backtrace is:
internal compiler error: in fold_convert_loc, bei fold-const.c:2357
