Interesting, I was seeing a lot of these Future::waitAndThrow crashes, but they stopped for me on 4 October, which is when the 3 October devprev build became available.

I haven't had any waitAndThrow crashes since then, and just a couple of the random UI crashes during hand folding. (The dreaded sticky pull or trying to move something are usually involved.)

I run each Foldit client in its own directory, so c:\Foldit1, c:\Foldit2, c:\Foldit3, and so on. Long ago, that seemed less crashy, or at least less confusing. Not sure if that would help, but it does help guarantee a clean log.txt, with messages from just one Foldit.

If you're seeing a lot of these crashes, maybe re-installing Foldit, or making a new installation in a new directory, would help. There was a problem with a missing prerequisite when the new system first launched, and that was fixed by an updated installer. Also, check Windows Update to see if there's an optional update. The Microsoft Visual C++ Redistributable was involved, but I'm not sure offhand which version was missing.

Thank you for your comments Loci, but these are all not applicable.
"Also, check Windows Update to see if there's an optional update. The Microsoft Visual C++ Redistributable was involved, but I'm not sure offhand which version was missing." I am aware of that, I reported that issue and also the fix.

The first line says "RtlAnsiStringToUnicodeString +402 bytes (no line)" so possibly the conversion of a string went wrong.
Also notice that the addresses repeat:
1: RtlAnsiStringToUnicodeString +402 bytes (no line)
2: HeapFree +10 bytes (no line)
3: xmlXIncludeSetFlags +747160 bytes (no line)
4: c10::ivalue::Future::waitAndThrow +46783174 bytes (no line)
repeats:
44: c10::ivalue::Future::waitAndThrow +45915328 bytes (no line)
45: c10::ivalue::Future::waitAndThrow +46782395 bytes (no line)
46: c10::ivalue::Future::waitAndThrow +46783156 bytes (no line)

I would look for a try-catch construction which fails internally where a conversion takes place. (Was a large enough buffer allocated ?)
