I cannot get a small code sample with or without a DLL to exhibit the
problem.  Like I said, I thought it was something related to size of my
DLL.  And this is the small DLL, only 3 MB.

 Regarding DLLs, I'm out... I don't think I have ever done one.
 Which toolchain are you using?  Msys/mingw64 is probably the
preferred one.  (Personally, I use cygwin for Windows stuff (with
the mingw64 cross compiler), but that is because I like the
UNIXy look and feel of cygwin.)
 Did you look at the symbols that can be found in the respective
DLLs, do they match your expectations?  (I presume you follow

 ).

For compilers and IDE, I am using GCC 14.1 that is in Simply Fortran 3.38.

For Unix utilities on Windows, I use the old Thompson Toolkit from 1987 that had the grep written in assembly language for SPEED.  Finding code in 5,000+ subroutines across 60+ subdirectories requires SPEED.
