Well the thing that I *think* should be on the other end of the pipe
crashes with a similar message:

warn:heap:HEAP_ValidateInUseArena Heap 40220000: invalid in-use arena magic for 40257990

The only other occurrance of that address (40257990) for the putative
server process is:

trace:heap:RtlAllocateHeap (0x40220000,00000002,00000108): returning 40257990

As I am a novice at this wine debugging malarchy, I don't know what an
arena is, much less its magic, so I have no idea how I might determine
if the application is currupting it or there is a wine bug.
(acknowledging of course that wine has *no* bugs ... :-P)

I think I have found a server binary (see above), but it crashes so I
am not sure. Can I use nm or something similar to look for calls to
whatever functions are likely to create the pipe, so as to at least
make sure I am dealing with the correct binary. (we have no
instructions yet...)

I get no err messages.

Is it reasonably safe therefore to assume that it would *like* this
dll, but doesn't *need* it.
