Invalid memory pointer read error causing window applicatin crash RRS feed

  • Question

  • Hi, 

     I am analyzing a crash dump of my window application which runs for 3 days and then crashes with "INVALID_POINTER_READ" error. below are the register details:

    CONTEXT:  (.ecxr)
    rax=0000000000000000 rbx=0000026591824f40 rcx=3465623838353134
    rdx=0000000000000000 rsi=0000000000000001 rdi=0000000000000000
    rip=00007ff6233470c4 rsp=0000007b25cff4c0 rbp=0000026591a72b98

    00007ff6`233470c4 488b09          mov     rcx,qword ptr [rcx] ds:34656238`38353134=????????????????
    Resetting default scope

    The call stack suggest, there is a signal call done with wxCondition::Signal() but the wxCondition* pointer contain bad or invalid address ":34656238`38353134" which rcx register is currently holding. 

    can someone suggest where to check which thread/process user or kernel causes this corruption of wxcondition* pointer variable.??
