Just for grins, does this work (same test): https://www.dropbox.com/s/x8dv5zgbh5...ime95.exe?dl=0
It is the exact same code but compiled without optimization. No need to send output  just a yes/no answer is fine. Thanks.

Firstly, lowering the n from 4344392810277*2^12900001, I get n=336101. Code:

I'm curious, does this case work:
[qa] SPECIFIC_K=4344392810277 SPECIFIC_B=2 SPECIFIC_N=1310720 SPECIFIC_C=1 CHECK_OFTEN=1 This is a rational zeropad FFT (the known bad cases are irrational zeropad FFT). A rational FFT occurs when the "n" in k*b^n+c is a multiple of the FFT length. In this case no weights need be applied.

Yes this works in 29.7b1 and in the first patch you released. I did not get the 2nd Prime95.exe and it is gone from dropbox. Code:

I have a fix!!!
The gwnum assembly code was violating the Windows 64bit ABI (not creating a 32byte shadow space on the stack) prior to calling C Code. This bug has been around forever. The AVX512 code calls the C code a little differently than the other FFTs and ran afoul of this bug. Thanks to ATH for creating a MSVC 2019 environment I could log into. I'll upload new executables and source soon.

Great! I'm happy it helped you. Let me know if you need the instance still, and do you need to save files from it? Edit: I will probably leave the instance up for testing your new exec, though I'm sure you already tested Last fiddled with by ATH on 20190408 at 13:55
