Bug ID: 82550
Summary: program using submodules fails to link
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran

The attached example implements a separate module procedure returning a
procedure pointer. gfortran 7,2 compiles the code, but issues the following
error message at the linking stage:
/gpfs/scratch/pr28fa/a2832ba/a2832ba/ccmqzru6.o: In function
`__m_subm_18_pos_MOD_foo':
subm_18_pos.f90:(.text+0x20): undefined reference to `p.3503'
It seems that host association to the module procedure p() fails, because
linking works if an external procedure is used.
