Reaper Crash - Unknown Module (RESOLVED)

[Edgemeal]

Faulting application name: reaper.exe, version: 5.9.5.0, time stamp: 0x5b96700c
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
Exception code: 0xc0000005
Fault offset: 0x00000000644cf540

Don't think I've ever had a crash where the module was unknown, whats that mean?

Link to the dmp file Windows created,

I also created (the much larger) dmp file from task manager before closing reaper if needed.

Win7 / v5.95 / x64

Thanks, Thats the plugin I was tweaking at the time, I can open the dmp file (VS 2015) but not sure what to look for.

Type these commands then enter after each one...

.symfix
knL
!analyze -v

Oops, can't remember where to do that in VS, those are the windbg commands. Here's what that looks like (abbreviated)...

Click on the "Debug with Native Only" button. It will start at the stack frame that crashed (0x644cf540, from the "unknown" module). You can see how it arrived there and from which module (AmpliTube 4.vpa) in the Call Stack window (with limited usefulness without debug symbols–.pdb– nor the source code).

Thanks, at least next time I can look to see what caused the crash. Amplitube4 is pretty stable unless I change pedals/effects really fast, tho this time I was just making tiny adjustments to an amp.

Can someone take a look at this Windows 7 dump file and tell me what actually is causing REAPER to crash? This is like the 5th crash in this one project. Each time was after an hour or so of editing and happens right after I stop/play, it happen in REAPER v5.965, v5.97, and v5.971.

In VS I see in the one list is like 4x reaper.wave.dll, then 4x jsfx. I swapped out all the JSFX for others but that didn't help.


dump file, (Rar) is 2.23 MB.

reaper_wave.dll divided an integer by zero (but there might be more to it given the odd -1 addresses in the call stack). Looks like you've found a REAPER bug.
