Bug ID: 82586
Summary: ICE: write_symbol(): bad module symbol

Version: 8.0
Status: UNCONFIRMED
Severity: normal

I recently did some tests with the very new PDT feature
to generate some tiny, disruptive test cases :
$ cat z1.f90
module m
type t(a)
end type
end
$ gfortran-8-20171015 -c z1.f90
f951: internal compiler error: write_symbol(): bad module symbol 'a'
