Note1: the tmad tests comparing to Fortran succeed (for HRDCOD=0). So I would guess that it is HRDCOD=1 that gives wrong results?
Note2: however, in PR #847, the CI actually fails the test for HRDCOD=0 (which should normally succeed??). So there is clearly something to be understood here.

Error: Process completed with exit code 1.
And, even more bizarre, the .mad tests succeed in the same CI, it is only the .sa tests that fail. (This was normally the same code I think?). So again something to be debugged...
Hi @zeniheisser , as discussed I have checked that my recent SUSY/HEFT/SMEFT patches make it possible to code generate EWdim6 u d~ to w+ z, thus fixing what you reported in #615.
The code also builds and runs. However I found a mismatch in the calculation of the ME between HRDCOD=0 and HRDCOD=1 (within runTest.exe in my "tput" test suite). If I use a reference file created with HRDCOD=1, then the test fails for HRDCOD=1, and I guess viceversa. I am not sure which one is correct. I will later on also compare to fortran.
The error is for instance the following:
The same failure happens for FPTYPE=d,f,m.
