             Bug #: 14111
           Summary: missing part of command in break error message
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
        AssignedTo: unassigned@sourceware.org
        ReportedBy: brobecker@gnat.com
    Classification: Unclassified


Consider the following dummy code in Ada:

    procedure P is
    begin
       null;
    end P;

Compile it using:

    % gnatmake -g p

Then try to insert a breakpoint on a given task, but with the wrong
capitalization for the "task" keyword; we get:

    % gdb p
    (gdb) start
    (gdb) b *p'address TASK 2
    Garbage 2 at end of command

The error message should say that `TASK 2' is the garbage in question. I will
submit a patch to fix this part soon.  But there is a second problem with
similar symptoms.  Once my patch is applied, the following scenario still
fails:

    (gdb) b *p'address TASK Task TasK 2
    Garbage `TasK 2' at end of command

... The quoted portion of the command is missing the first couple of invalid
keywords.  The problem is different because it's not find_condition_and_thread
that skips these keywords and ignores them, but something before that.

It's probably happening while in the linespec parser, but I don't know whether
the linespec parser might rely on the language to find the end of the
breakpoint location or not. To be investigated further...

This is the URL of the proposed fix for the first failure scenario:
