Fortran regression in OpenWatcom for MS-DOS ?

[ijean]

Hello,

I've compiled this small program under DosBox:

       program test2
       implicit none
       real*8 x, y
       x = 3.15d0
       y = dsin(x)
       print*, x, y
       end

With latest OpenWatcom release (from beginning of December 2025) the result unexpectedly was:

    0.00000000000 0.00000000

Same program built with OpenWatcom 1.9 gives the expected results.

In both cases I've used DosBox 0.74-3-3 which hasn't changed since 2020. I suppose there was a regression at some point, because at least the value of x when printed should be different from 0.

Thanks for keeping OpenWatcom alive,
Jean

It is known problem for OW 2.0 32-bit version of compiler (for all hosts).
64-bit version (Windows and Linux host) is unafected.
We are working on fixing it just now.
