Subject: Breakpoint loss under low memory conditions
Date: Tue, 20 Nov 2018 07:31:00 -0000 [thread overview]
Message-ID: <25100483E4CD1F4087B0A40EBF04FFBD1D5BE7B7@DENBGAT9EH3MSX.ww902.siemens.net> (raw)
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 ?
Regards
Walter Stoll
