Exception 0D with 2019 release

[steve]

Hi Jos,

I tried running my program with the new release  (2019) and instantly got the following:

UNHANDLED EXCEPTION 0D at 01E7:3E23 Error code: 0824
AX = 000D   BX = 4010   CX = 0000   DX = 0827
SI = 0556   DI = 0F12   BP = 0FA6   SP = 0F98
CS = 01E7   Limit = 81E0 segment #01 of C:\OPS-EXES\OPS-513F.EXE
DS = 0CBF   Limit = BFC0 segment #AE of C:\OPS-EXES\OPS-513F.EXE
ES = 0827   Limit = 0EC5 segment #64 of C:\OPS-EXES\OPS-513F.EXE
SS = 0D0F   Limit = 0FFF
- 01E7:3E1B  0A C0 74 12 3C 25 74 11 36 88 05 47 FE 4E EC 7F

(the format is slightly screwed as I had to take a snapshot of the screen and then use Google Note to OCR the JPEG produced).

I ran with the /LOG option and the LOG file is attached.... vDos.log (232.16 KB)

The same program has been working under the 2018 release without giving an exception. I reran the program on the 2018 release and the compressed log file is also attached... vDos.log.7z (12.62 KB)

Does anything spring immediately to mind?

Cheers,
Steve

In the offending instruction (MOV SS:[DI],AL) ES instead of the SS segment will be referenced. And DI (0F12) falls outside the limits.
I’ll send you a (hopefully) corrected vDos.exe by wetransfer. If you could test that and report back.

Hi Jos,

Tried the version. It did not report an exception, but just hung (had to kill it with task manager). Attached is the Log file created... vDos.log (205.37 KB)

Hi Jos,
2nd version - No problems so far. I shall put it through it's paces. Thank you.

Hi Jos
Latest version seems to work well apart from a problem with BEEP.WAV.

I shall start another thread when I have some timings as I suspect not many people will be worried about this.
