Fortran: error recovery on invalid array section [PR108609]
The testcase for PR108527 uncovered a latent issue with invalid array sections that resulted in different paths being taken on different architectures. Detect the invalid array declaration for a clean recovery. gcc/fortran/ChangeLog: PR fortran/108609 * expr.cc (find_array_section): Add check to prevent interpreting an mpz non-integer constant as an integer. gcc/testsuite/ChangeLog: PR fortran/108609 * gfortran.dg/pr108527.f90: Adjust test pattern.
