             Bug #: 13798
           Summary: regression: can't set breakpoint for filepath
                    containing space (Error in re-setting breakpoint:
                    Function not defined)
           Product: gdb
           Version: 7.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
        AssignedTo: unassigned@sourceware.org
        ReportedBy: niko.sams@gmail.com
    Classification: Unclassified


Since gdb 7.4 setting breakpoint for a filepath containing spaces doesn't work
anymore. See the following example:

niko@niko-home:~$ cat space\ spaces.c 
#include <stdio.h>

int tmp(void) {
    int a = 42;
    printf("%d", a);
}

int main(void) {
    tmp();

    return 0;
}

#gdb 7.3.1 works fine:
niko@niko-home:~$ gdb a.out
