Besides finding the wrong file, another possible explanation
is that there is a mismatch between the array sizes in texmf.cnf
that were used during mem dump time and the sizes that are to be
used runtime. The 0.993 beta checks these values to make sure
there is no change.
This can happen for instance when you have a texmf.cnf like
this:
main_memory.mpost = 100000
main_memory.metafun = 2000000
In both cases, the -kpathsea-debug switch is useful. Either on
the commandline, or in the environment.
mpost -kpathsea-debug=6
or
KPATHSEA_DEBUG=6
export KPATHSEA_DEBUG
mpost
The numeric value is a bitfield, the combination '6' should give
you file operations and texmf.cnf value lookups
Good luck,
Taco
