The debugger sometimes fails to re-set a breakpoint as follow,
causing it to become disabled:
(gdb) b nested_sub
Breakpoint 1 at 0x401cec: file foo.adb, line 7.
(gdb) b do_nothing
Breakpoint 2 at 0x401cdc: file pck.adb, line 4.
(gdb) run
Starting program: /[...]/foo
Error in re-setting breakpoint 1: Function "nested_sub" not defined.
Breakpoint 2, pck.do_nothing () at pck.adb:4
4 null;
This only happens on machines where the debug-file-directory is
a valid directory name.
The reason behind the error is that the linespec code that re-sets
the breakpoints uses the current_language global when iterating
over a symtab's symbols. However, the that global gets switched from
Ada to C during the startup phase, probably as a side-effect of stopping
in some system code for which debugging info is available. The fix
is to make sure that we use the correct language.
gdb/ChangeLog:
* linespec.c (iterate_over_all_matching_symtabs): Use the correct
language when iterating over symbols.
gdb/testsuite/ChangeLog:
* gdb.ada/bp_reset: New testcase.
