Crash with SDRPlay #9

Open gvanem opened 4 years ago

gvanem commented 4 years ago

I just discovered PLSDR and tried it with my own MSVC-2019 (32-bit) build of GnuRadio 3.9 (+Python 2.7). It works fine using osmo-sdr, but often (not always), it crashes when switching to a SDRPlay device.

I have both a SDRPlay RSP1A and a RTL-SDR stick attached to my computer.

Details from WinDbg (my JIT debugger):

Access violation - code c0000005 (!!! second chance !!!)
eax=8c001ed6 ebx=00000000 ecx=3c8cdeac edx=15b0fa30 esi=0fee0000 edi=15b0fa28

ntdll!RtlpFreeHeapInternal+0x2c2:
7753681a 8b7104          mov     esi,dword ptr [ecx+4] ds:002b:3c8cdeb0=????????

From the WinDbg module-list, the [exc+4] address looks illegal. And the call-stack:

ntdll!RtlpFreeHeapInternal+0x2c2
ntdll!RtlFreeHeap+0x46
MSVCR100!free(void * pBlock = 0x15b0fa30)+0x1c
QtCore!initQtCore+0xf8add

Qt5Gui!QGuiApplicationPrivate::processMouseEvent+0xa22
Qt5Core!QMetaProperty::writeOnGadget+0x342c
Qt5Core!QMetaType::typeInfo+0x6f

I guess PyQt5\QtCore.pyd is causing this somewhere (since it's using MSVC100.DLL while my normal Qt5 is using something newer).

BTW. It is really a cool program!

Edit: Doing an !analyze -v in WinDbg showed: FAILURE_ID_HASH_STRING: um:heap_corruption_c0000005_heap_corruption!python.exe No shit Sherlock.

Update: here is longer call-stack that goes back all the way to PLSDR.py:
