I tested.

A debug build of Revision 237 source:/OCO/trunk#237 does not trap. A debug build of Revision 238 source:/OCO/trunk#238 traps.

Changeset [238] is "Mike's new build system, switch to wasm and use Mike's new OWDDK"

It would be good to try to break this changeset down and see which part of it causes the trap. There are code changes, makefile changes, a new set of DDK changes, a change in linker, and a change in assembler.

[Brendan Oakley]

Replying to gentux2:

a new set of DDK changes,

Sorry I meant a new set of DDK headers, not changes.

Problem is in mif\drvmake.mif creating uniaud16.lnk. Current file reads:

!ifdef DEBUG

@%write $^{@ segment _DEBUGTEXT PRELOAD SHARED IOPL READWRITE}

!endif

But should be:

!ifdef %DEBUG

@%write $^{@ segment _DEBUGTEXT PRELOAD SHARED IOPL READWRITE}

!endif

Segment option was not being included in DEBUG build causing the code to be discarded after INIT and leading to a TRAP D.

Fix verified on my system, and once Allan verifies, recommend committing and closing.

!ifdef %DEBUG

I can confirm, that debug build is now working with this fix.

fixed in changeset:264

One down, more to go :)
