Gdb Cannot Insert Breakpoint Cannot Access Memory At Address
Subject: Cannot insert breakpoint -1. Hello, Is there a reason why gdb break cannot access memory at address GDB will try to set a breakpoint (breakpoint number: -1) at the entry point address on a gdb cannot insert breakpoint 0 'c', after a 'target remote'? (I am using a GDB stub at the remote end that resides in a hypervisor upon which guest OS'es run). I am

I'm trying to debug a C++ module across JNI from a JUnit. 1. I launch my "JUnit" debug config and successfully breakpoint immediately after my System.loadLibrary(mysharedlib). 2. I then launch my "C/C++ Attach to Application" debug config, which is defined as: - Application=Debug/libmysharedlib.so - Build config=debug - Debugger=gdb - Non-stop mode=off (although this cannot insert breakpoint setting makes no difference) This Attach to Application launches, I then attach it to javaw properly, and I see 13 suspended threads. 3. I then attempt to resume C++ thread #1 (state=suspended: user request) to no avail. - Entering "info break" from the gdb console correctly shows my breakpoint in the C++ code. Further, I can successfully display code in my C++ module, so I know I have debug info present. - Entering "c" from the gdb console gives: Warning: Cannot insert breakpoint 1. Error accessing memory address 0x2da6: Input/output error. 4. When I then attempt to resume the JUnit thread, I get the expected "org.eclipse.jdi.TimeoutException: Timeout occurred while waiting for packet 622. occurred resuming thread." as it appears all C++ threads are still suspended. The workspace/.metadata/.log yields messages like: !ENTRY org.eclipse.cdt.dsf 4 10005 2011-06-13 12:06:55.727 !MESSAGE Request for monitor: 'RequestMonitor (org.eclipse.cdt.dsf.concurrent.RequestMonitor@68446844): Status ERROR: org.eclipse.cdt.dsf.gdb code=10004 Failed to execute MI command: -exec-continue Error message from debugger back end: Warning: Cannot insert breakpoint 1.
