             Bug #: 14657
           Summary: quotes in breakpoint linespec not saved
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
        AssignedTo: unassigned@sourceware.org
        ReportedBy: dje@google.com
    Classification: Unclassified


This was discovered while working on bug 14643.

In a gdb that has bug 14643, e.g. 7.5, one should be able to work around the
problem by quoting the file name.
However the quotes are discarded, so while the "break" command succeeds,
resetting the breakpoint, e.g. when the program is run, fails.

bash$ gdb thread.c
GNU gdb (GDB) 7.5
[...]
(gdb) b thread-exit.c:42
malformed linespec error: unexpected keyword, "thread"
(gdb) b 'thread-exit.c':42
Breakpoint 1 at 0x400a28: file thread-exit.c, line 42.
(gdb) r
Starting program: /home/dje/src/play/thread-exit.x64
Error in re-setting breakpoint 1: malformed linespec error: unexpected keyword,
"thread"
(gdb) i b
Num     Type           Disp Enb Address            What
1       breakpoint     keep n   0x0000000000400a28 in main at thread-exit.c:42

If a quote was supplied when the breakpoint was set, it should not be
discarded.

[There is a plan to parse and save linespecs into their component pieces.
Not sure when that will happen, and if we should fix this in the mean time.]
