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?

To me this looks like a regression in gdb 7.4. I reported the bug: http://sourceware.org/bugzilla/show_bug.cgi?id=13798
适用于我（tm），但并未尝试使用c ++ ...
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
