Hi,
Really bad things happen if the variable name in metapost contains an
underscore. It took me quite a while to isolate this problem.
Minimal example:
\startMPinclusions
input rboxes ;
\stopMPinclusions
\starttext
\startMPpage
rboxit.A (textext("A")) ;
rboxit.B_1 (textext("B")) ;
rboxit.C (textext("C")) ;
A.c = origin ;
xpart B_1.c = xpart C.c = xpart A.c + 3cm ;
ypart B_1.s - ypart C.n = 1cm ;
drawboxed(A,B_1,C) ;
\stopMPpage
\startMPpage
rboxit.A (textext("A")) ;
rboxit.B (textext("B")) ;
rboxit.C (textext("C")) ;
A.c = origin ;
xpart B.c = xpart C.c = xpart A.c + 3cm ;
ypart B.s - ypart C.n = 1cm ;
drawboxed(A,B,C) ;
\stopMPpage
\stoptext
See attached output. The label of box B is placed at origin rather than at
the correct location!
I am using 2010.08.17 and luatex 0.61 (too close to a deadline to
update).
Aditya

This is getting weirder. The bug is triggered even for the following
example:
\startMPpage
rboxit.A (textext("A")) ;
rboxit.B1 (textext("B")) ;
rboxit.B2 (textext("C")) ;
A.c = origin ;
xpart B1.c = xpart B2.c = xpart A.c + 3cm ;
ypart B1.s - ypart B2.n = 1cm ;
drawboxed(A,B1,B2) ;
\stopMPpage
but disappears if I replace B1 with Ba and B2 with Bb!

The metapost string comparisons were broken until luatex 0.63.
Best wishes,
