a very unfortunate bug ... i will talk to Herb about this since it can
be fixed in offline. But, as of now (somewhere after run 4021037) the
problem is fixed and no more offline tricks are required.

i looked into the assert() error and found a header inconsistency in the
TOFP bank (the banklength only included the header length and not the
full bank length). This has to be (and is) solved in the daq software
for TOF.
The assert() in the fast-offline discovered this inconsistency and
seg-faulted the job. Contrary to what I claimed below, this is unrelated
to the increase in datawords for TOF in this year's run.
To (fast-offline) analyze the data that has been taken so far, I suggest
temporarily disabling the assert() check for TOFP banks in
EventReader.cxx. Actually quite a few banks have already exempted
themselves from these checks!. All data taken as of this very minute
will have consistent bank headers again and keeping such consistency
checks proofed to be very helpfull
