Description
Caused by commit 9d88da6c2b, if I add or remove a breakpoint while a 32-bit console application is running, QtC loses connection with the debugger, it considers the application as "stopped", and any attempt to continue results in a timeout after some time. Needless to say, the breakpoint doesn't break.
Attached the relevant part of the logs. Notice that with QtC 13 the logs shows:
>~"37 received signal SIGTRAP, Trace/breakpoint trap.\n" >~"[Switching to Thread 4324.0xa8b4]\n" >~"0x77474e21 in ntdll!DbgBreakPoint () from C:\\WINDOWS\\SysWOW64\\ntdll.dll\n" >*stopped,reason="signal-received",signal-name="SIGTRAP",signal-meaning="Trace/breakpoint trap",frame={addr="0x77474e21",func="ntdll!DbgBreakPoint",args=[],from="C:\\WINDOWS\\SysWOW64\\ntdll.dll",arch="i386"},thread-id="37",stopped-threads="all" d[GDB] NOTE: INFERIOR STOP OK Stopped. d[GDB] State changed from InferiorStopOk(10) to InferiorStopOk(10) [GDB] HANDLING QUEUED COMMANDS AFTER TEMPORARY STOP <27-break-insert -f "\"SIPTrunkSettingsJsonModels.cpp\":30"
While with 14 it is:
>~"[Thread 35260.0x755c exited with code 0]\n" [Thread 35260.0x755c exited with code 0] >=thread-exited,id="37",group-id="i1" Thread 37 in group i1 exited. --- token barrier --- d[GDB] NOTE: INFERIOR RUN REQUESTED Run requested... d[GDB] State changed from InferiorStopOk(10) to InferiorRunRequested(6) Running requested... <1949-exec-continue>=thread-created,id="38",group-id="i1" Thread 38 created. >~"[New Thread 35260.0x834c]\n" [New Thread 35260.0x834c] >=thread-created,id="39",group-id="i1" Thread 39 created. >~"[New Thread 35260.0x8760]\n" [New Thread 35260.0x8760]d[GDB] 1949: -exec-continue d[GDB] TIMED OUT WAITING FOR GDB REPLY. COMMANDS STILL IN PROGRESS: "-exec-continue"
Reverting 9d88da6c2b completely (it was partially reverted in 2364448f910) fixes the issue for me.
