With test-case gdb.fortran/logical.exp, I run into: ... (gdb) PASS: gdb.fortran/logical.exp: var=l: get hexadecimal valueof "&l" set *((uint8_t *) 0x7fffffffd2bc) = 0xff^M No symbol "uint8_t" in current context.^M (gdb) FAIL: gdb.fortran/logical.exp: var=l: byte 0: set contents of byte at offset 0 ... Fix this by using the fortran-native type character instead. Tested on x86_64-linux, with gcc 7.5.0. gdb/testsuite/ChangeLog: 2020-03-11 Tom de Vries <tdevries@suse.de> * gdb.fortran/logical.f90: Define variable with character type. * gdb.fortran/logical.exp: Use character type instead of uint8_t.
