John, Earlier this week I merged a change in ParaView that uses the latest (not yet released) version of IceT. You have the dubious honor of reporting the first problem.
It appears that the MSVC debugger is checking to make sure variables are set
before used as an argument to a function. (Cool feature. I didn't know it did
that.) It looks like I violated that. I am pretty sure this is benign; the
state that leads to uninitialized variables should mean they won't be used in
the function. It's still bad and dangerous practice though, so thanks for
pointing it out.
Attached is a patch that should fix the problem. Please apply it to reduce.c
and let me know if it resolves the problem.

Subject: [Paraview] IceT problem
When running in parallel on windows, I get this (frequently)
I just closed the debugger and forgot to copy the stack trace, but can post it
if it helps.
Is it a known issue? (I’m using IceT master, head of current git from the
paraview repo) – can I just set piece offset to the process rank?
Line 109 of reduce.c
if (icetIsEnabled(ICET_COLLECT_IMAGES)) {
result_image = reduceCollect(composited_image,
compose_tile,
piece_offset);
