Re: Error : Lilypond version 2.19.55 Error invoked

[Christian Masser]

Hi Jean!

I got a similar error two days ago with a pretty basic file, nothing fancy at all. (To be precise: changing "des2." to "des2. ~ des" produced the error.)

After switching to the then up-to-date dev-version (from "2.22.0-2" to "2.23b30375.2e8c87df0f-1" on arch linux) the error went away. Would backtracing it still help you in any way?

All the best

Christian

Dear community:

I am reaching out for assistance in regard to the following error.  

Although I regard my knowledge of Lilypond to be primary, I have been a more than excited user for over two years now, and have never come across an error which I could not 'somehow' work around, at least until now.

The following error was reported and archived in 2009, by another user (JUNE 3 2019, (2.19.82).

However, I have been unable to find its resolution in the Archive. The error has now happened to my code, and I require some assistance to get by it.

I am using MAC OS 10.13.6 HIgh Sierra, and Lilypond 2.19.55

The compile and subsequent engraver output fails, unless I replace a 'note' with a rest.

ERROR :

v/Parsing...Interpreting music...[8][16][24][32][40][48][56]ERROR: In procedure ly:trampoline:ERROR: Wrong type argument in position 3 (expecting Translator): #<freed cell 0x5e6cb90; GC missed a reference>Exited with return code 1

I provide a clip of the code below where the error is invoked, as shown in between 

the 2 % % marks. The error seems to point to the 2nd last note the 'flagged' measure.

Please note that if I replace that beat with an r8, the compile and engraver run successfully.  

If I leave a note in that position, the error is invoked.

It appears to me, as noted in this email, that the same error had been reported in June 2019.

Also, I am using in this piece the Add Lyrics functionality.

An assistance will be most appreciated.

Hello,

This is a garbage collection error. The bug is rooted in
LilyPond's hard core written in C++, so there is not much
that you can do as a user to fix it. Sorry.

What you can do is help understand the problem:

- Does it reproduce with recent versions? LilyPond 2.22
  is a stable version and was released weeks ago. A ton of
  bugs have been fixed since version 2.19.55!

- If not, could you please post your complete code, if
  that is possible regarding copyright, etc.? This way,
  others can try to reproduce it on other machines.

- If not, would you mind sending it to me privately? I
  can confidentially look for unusual code.

- If you do mind: do you have experience with using GDB?

Thank you,
Jean Abou Samra
