I have just released Jumbo 0.6.64 . Versions 0.6.63 and 0.6.62 should not be used, they are crashing and/or not working reliably.
http://www.schuelebln.de/chess/jumbo
@joechess: I am not sure whether this solves your problem since I can't reproduce your "illegal instruction" error on my hardware. But I found another crash which I fixed with the new version. So could you please try again with 0.6.64 using the binary "jumbo64-0.6.64-bb-sse41.exe"?
Jumbo 0.6.62 is out

Re: Jumbo 0.6.62 is out
Sven, I think compiling with -march=barcelona would solve joechess' crashes, because that's the microarchitecture of his CPU. -msse4a should work too if that's an option. The next step down is -mssse3 but that drops the POPCNT instruction.
If you're still compiling with -msse4.1 Jumbo will keep crashing on his notebook. Or did you merely forget to rename the exec?

Compile flag differences are as follows for the public Jumbo versions:tpoppins wrote: ↑Fri Nov 02, 2018 7:38 am Sven, I think compiling with -march=barcelona would solve joechess' crashes, because that's the microarchitecture of his CPU. -msse4a should work too if that's an option.

a) Up to Jumbo 0.6.51 there were no special compile or linker flags related to certain hardware platforms (just Windows 64 bit). As far as I understood, these binaries were working for "joechess".
b) Starting with Jumbo 0.6.62 the following flags were added to achieve a noticeable speedup and strength increase:
-flto (for all 64-bit binaries)
-msse4.2 (for "jumbo64-VERSION-bb.exe")
The "jumbo64-VERSION-bb-sse41.exe" binary is compiled without "-msse4.2" flag (but not with any "-msseXXX" flag instead). Obviously the name is misleading, the meaning is more like "before SSE 4.2".
I am not willing to provide special binaries for all sorts of special hardware. If the "sse41" binary of 0.6.64 does not work for him but the standard binary for 0.6.51 and earlier were working then the reason might be the "-flto" flag.

Re: Jumbo 0.6.62 is out
Are you sure sse3 drops the POPCNT instruction? I did a test with sse3 and it uses the "popq" instruction.

Isn't popq about restoring registers after a subroutine call?D Sceviour wrote: ↑Fri Nov 02, 2018 2:22 pmAre you sure sse3 drops the POPCNT instruction? I did a test with sse3 and it uses the "popq" instruction.
Anyway, to my knowledge POPCNT was introduced with SSE4.2. Since Jumbo uses the GCC intrinsic function __builtin_popcountll(), it will automatically use the POPCNT instruction if available, otherwise the substitute implementation provided by the compiler.

Sorry, it should have been "popcntq".
