Do not crash when calling GDB with empty executable name. % gdb -q '' ... or ... % gdb -q (gdb) file '' ... both cause GDB to crash with an invalid free. This is because exec_file_attach is attempting to free a string that has not been allocated. The string is only allocated if openp is successful. But in the case of this obviously invalid filename, openp fails, and leaves scratch_pathname uninitialized, thus causing the xfree to fail. The fix is to enable the associated cleanup after we have verified that openp was successful. gdb/ChangeLog (By Keith Seitz <keiths@redhat.com>): * exec.c (exec_file_attach): Move cleanup after verifying that memory has in fact been allocated. gdb/testsuite/ChangeLog: * gdb.base/empty_exe.exp: New testcase. 2012-11-27 01:41:44 +08:00
