Breakpoint loss under low memory conditions

[Stoll, Walter]

Ladies and Gentlemen

Under low memory conditions, the Linux kernel may evict pages that contain executable code sections. If such a page was modified by a breakpoint, then the breakpoint will get lost when the page is finally faulted in. Is this a scenario that can happen in reality or does gdb and/or the kernel provide some means which prevent this from happening ?
