Bug ID: 114019
Summary: allocation with source of deferred character length
entity
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: kargl at gcc dot gnu.org
Target Milestone: ---
Found this issues with the Fujitsu testsuite. The code
is reduced to the minimum required. If I had to guess,
gfc_charlen for source= is not set correctly.

! Reduced from Fortran/0069/0069_0037.f90
