Hi Oscar,
> is this correct, that lilypond has this "security issue" as stated;
I'm no security expert, but this issue has been discussed at length several
times on the Lilypond lists (-user and -dev), so check the archives.

Probably... what about
\repeat "unfold" 10000000 { \repeat "unfold" 10000000 { \repeat "unfold"
10000000 { \repeat "unfold" 10000000 { c128 } } } }
Worse, of course, is to write in a Scheme function -- which Lilypond would of
course attempt to execute -- which simply calculated pi to infinite precision.
=)
Cheers,
