Cryptical errormessage

[Hans de Rijck]

Hi,

I get an errormessage that I don't understand, the last lines of
lilypond --verbose are:

abnormal program termination

Are the numbers in square brackets after 'Element count' barnumbers? In the
lines above they are. But measures 1 to 30 are only full measure rests with
no markups.

The assertion message isn't very meaningful too, its logical the result is
'false', otherwise the assertion wouldn't have failed. It would be more
helpful to print what the assertion was.

Any ideas how to find the meaning of the above or how to debug this?

Apart from the message above there are no warnings or errors.

regards,

Hans.
