ERR* CP-09 dynamic memory not freed

[pkapas]

Hello,

I am trying to compile a Fortran source code using Open Watcom Fortran 77 v2 , which was working (generating .exe file) using original WATCOM Fortran 77 version 11, but the wfc386 ends up with ERR* CP-09 message, before starting linker. The Fortran source is in the file attachment.
I am using IDE environment. The Open Watcom Fortran 77 was installed following default setup, wit modification of local environmental variables, but how I can see, those modification was not made, size of autoexec.bat and config sys are ZERO.

OS: Windows XP Professional
Virtual Machine: 86Box (latest version)

wfc386 homogen.for -fo=.obj -d2 -bm -q -dep

Addition to this issue. Finally I found way to run compilation and debugging. BUT!!! There is a very serious issue in internal and external debugger, related to WRITE (6, ...) R, where R is a floating point variable or for example WRITE (6, ...) 12.345 It is present in Windows XP using 86Box emulator. This issue is not present in Windows 98 or in Windows XP installed in VMware emulator. Printing Integer or string variables are fine, no issue, works correctly.

So, ... On 86Box (latest, 5.3), Windows XP, in case of WRITE, PRINT, if printing real (floating point) variable, number

F10 (Step Over WRITE) → FAIL
F8 (Trace Into WRITE) → OK
Normal run → OK

That strongly suggests this is not just “FPU instability”, but a very specific debugger execution-path bug involving procedure call handling + stepping mode semantics.

Both, Open Watcom Fortran 77 v2 and Classic Watcom Fortran v11.0a...c internal and external debuggers

Please, use example, attached to previous comment!
