! { dg-do run }
! Tests the fix for PR26393, in which an ICE would occur in trans-decl.c
! (gfc_get_symbol_decl) because anzKomponenten is not referenced in the
! interface for solveCConvert. The solution was to assert that the symbol
! is either referenced or in an interface body.
!
! Based on the testcase in the PR.
