This commit fixes a double-free bug in the GCC Fortran compiler when an ASSOCIATE construct’s selector is an allocatable, deferred-length character function. Previously, an extra free operation was unconditionally applied, but this is only necessary for POINTER-valued character functions. The fix ensures that the extra free is only performed when a POINTER is involved, preventing memory corruption, as allocatable function results are already released by their own cleanup routines.
