During the Variable View test (http://wiki.eclipse.org/index.php?title=PTP/testing/1.x), a dialog popped up with the error 'Error on tasks:0 - Callback in progress'. The icon for process 0 was changed to the error icon. The console output was as follows: <is4,1>, name: var2, tasks: 0 *** SEND COMMAND: Get Partial AIF: argv, tasks: 0 <0000002b GPA 5:343a303100 5:6172677600 2:3000 2:3000> ++++++++++ ptp_orte_proxy: ---------------------- GDBGetPartialAIF found key: va r3, format: v0 ======= void: v0 got debug event: EVENT_DBG_PARTIAL_AIF 01 <v0,(No value)>, name: var3 *** SET COMMAND RETURN: Get Partial AIF: argv, result: EVENT_DBG_PARTIAL_AIF 01 <v0,(No value)>, name: var3, tasks: 0 *** SEND COMMAND: Get Partial AIF: i, tasks: 0 <00000025 GPA 5:343a303100 2:6900 2:3000 2:3000> ++++++++++ ptp_orte_proxy: ---------------------- GDBGetPartialAIF found key: va r4, format: is4 ======= int: is4, size: 4 got debug event: EVENT_DBG_PARTIAL_AIF 01 <is4,-1208498312>, name: var4 *** SET COMMAND RETURN: Get Partial AIF: i, result: EVENT_DBG_PARTIAL_AIF 01 <is 4,-1208498312>, name: var4, tasks: 0 *** SEND COMMAND: Step over, tasks: 0-3 ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.InferiorResu medEvent@1a06642 <0000001e STP 5:343a306600 2:3100 2:3100> got debug event: EVENT_DBG_STEP 0e 0 org.eclipse.ptp.debug.external.core.cdi.Loc ator@47fb00 ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.EndSteppingR angeEvent@1afe733 got debug event: EVENT_DBG_STEP 01 0 org.eclipse.ptp.debug.external.core.cdi.Loc ator@174009b ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.EndSteppingR angeEvent@502d56 *** SEND COMMAND: Get Info Thread, tasks: 0 <00000010 ITH 5:343a303100> got debug event: EVENT_DBG_THREADS: 01 {1} *** SET COMMAND RETURN: Get Info Thread, result: [Ljava.lang.String;@17a4a80, ta sks: 0 *** SEND COMMAND: Get stack info depth, tasks: 0 <00000010 SID 5:343a303100> got debug event: EVENT_DBG_STACK_INFO_DEPTH 01 *** SET COMMAND RETURN: Get stack info depth, result: 1, tasks: 0 *** SEND COMMAND: List stack frames, tasks: 0 <0000001e LSF 5:343a303100 2:3000 2:3100> got debug event: EVENT_DBG_FRAMES 01 0 org.eclipse.ptp.debug.external.core.cdi.Locator@220e8b *** SET COMMAND RETURN: List stack frames, result: [Lorg.eclipse.ptp.debug.exter nal.core.proxy.ProxyDebugStackframe;@1e8f4e1, tasks: 0 ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.VarChangedEv ent@f7fded ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.VarChangedEv ent@14012b3 *** SEND COMMAND: List arguments, tasks: 0 <0000001e LAR 5:343a303100 2:3000 2:3000> got debug event: EVENT_DBG_ARGS 01 {argc, argv} *** SET COMMAND RETURN: List arguments, result: [Ljava.lang.String;@e4c825, task s: 0 *** SEND COMMAND: Step over, tasks: 0-3 ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.InferiorResu medEvent@101044 <0000001e STP 5:343a306600 2:3100 2:3100> *** SEND COMMAND: List local variables, tasks: 0 *** SEND COMMAND: Get Partial AIF: var2, tasks: 0 *** SEND COMMAND: Get Partial AIF: var3, tasks: 0 ++++++++++ ptp_orte_proxy: ------------------- SendCommandWait sess->out_fd = -1 ++++++++++ ptp_orte_proxy: ++++++++++ ptp_orte_proxy: ------------------- GetChangedVariables error ++++++++++ ptp_orte_proxy: got debug event: EVENT_DBG_STEP 0f 0 org.eclipse.ptp.debug.external.core.cdi.Loc ator@18c93dc ***** Debugger event: org.eclipse.ptp.debug.external.core.cdi.event.EndSteppingR angeEvent@3f67e0 *** SEND COMMAND: Get Info Thread, tasks: 0 <00000010 ITH 5:343a303100> ++++++++++ ptp_orte_proxy: ------------------- SendCommandWait sess->out_fd = -1 ++++++++++ ptp_orte_proxy: ++++++++++ ptp_orte_proxy: ------------------- GDBMIGetInfoThread error ++++++++++ ptp_orte_proxy: got debug event: EVENT_DBG_ERROR 01 6 Callback in progress *** SET COMMAND RETURN: Get Info Thread, result: org.eclipse.ptp.debug.core.cdi.

This is a bug in GCC 4.0 that causes gdb to fail. It only affects gdb > 6.3, linux, x86 systems. The fix is to disable displaying local variables in main() for this architecture. Apparently the gdb failure will be fixed in 6.6.
I get this too. I have gdb 6.5.
The latest build should fix this problem. Are you testing with the latest build? (In reply to comment #2) > I get this too. I have gdb 6.5. >
