Hi List,
I have the following passage:
--------------------
\version "2.19.82"
\relative c'' {
\time 4/8
| %45
d32\( b g d \repeat tremolo 4 { b32 } \repeat tremolo 8 { g32 }
| %46
\repeat tremolo 8 { d'32 } \repeat tremolo 8 { g,32\) }
}
--------------------------
It compiles fine. But if I move it up one octave -- either by changing
the
enclosing command to \relative c''' or by changing the first note to
d'32\(, it fails with the following error:

failed.
Exited with return code 6.
I do not have a directory named "/home/gub".
Any ideas what's going wrong here?
That's a failing assertion in the code. The path is to the compiled
file when it was built, so it is not relevant to your filesystem.
Ultimately this is a programming error; but unfortunately, this is at
the C++ level, so it would require a new build of LilyPond to address.
A similar issue was reported not too long ago regarding tremolos and
beams. I found via some experimentation that too short of a note stem
can trigger the failing assertion. You could try manually lengthening
the stem to see if it helps as a possible workaround.
