GDB/MI: crash printing "_task" (Ada) argument In GDB/MI mode, trying to print the arguments of the frame corresponding to the body of a task ("-stack-list-arguments 1") causes the debugger to crash. This is because the compiler adds an implicit argument to that task body called "_task". mi/mi-cmd-stack.c:list_args_or_locals, which is responsible for printing the value of our arguments, finds that our "_task" symbol is an argument, and thus tries to fing the non-argument equivalent: if (SYMBOL_IS_ARGUMENT (sym)) sym2 = lookup_symbol (SYMBOL_NATURAL_NAME (sym), block, VAR_DOMAIN, (int *) NULL); Unfortunately, it tries using the natural name, which doesn't always work for Ada parameters, in particular those who are internally- generated. In our case, The "_task" parameter's natural name is "<_task>", and that symbol does not exist. So sym2 is NULL, thus causing the crash a little later on when trying to dereference it. We should be using the symbol linkage name in this case, the same way iterate_over_block_arg_vars already does. gdb/ChangeLog: * mi/mi-cmd-stack.c (list_args_or_locals): For argument symbols, use SYMBOL_LINKAGE_NAME to find the corresponding non-argument symbol. Add assertion that sym2 is never NULL. gdb/testsuite/ChangeLog: * gdb.ada/mi_task_arg: New testcase.
