gdb: how to set a breakpoint in a file with spaces

How does one set a breakpoint in a file that has a space in its filename or path?

It seems like this is not possible with GDB or am I missing something?

/tmp$ g++ -g debugee\ space.cpp 
/tmp$ gdb ./a.out

To me this looks like a regression in gdb 7.4. I reported the bug: http://sourceware.org/bugzilla/show_bug.cgi?id=13798

works for me (tm), didn't try with c++ though...

cat space\ spaces.c 
#include <stdio.h>

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

int main(void) {
    tmp();

    return 0;
}

$ gdb -q a.out
