Hello lilypond crew!

Reporting the bug here, since I saw on the bug link that you prefer mail over GitLab issues.

When trying to process any file with \layout{} directive, lilypond crashes (Segmentation fault / address not mapped).

I was able to reproduce it on current git master (2c9361d3d2d9e9bdfca626d01076c94fb81e2e88) as well.

My distro: Gentoo Linux

Installed (possibly relevant) library versions:

[IP-] [ ] dev-scheme/guile-2.2.7:12/2.2-1

[IP-] [ ] x11-libs/pango-1.42.4-r2:0

[IP-] [ ] dev-libs/boehm-gc-8.0.4:0

typescript.txt contains colored output (made with `script` utility, contains ANSI escapes, view best with cat or less -R) from lilypond being run under AddressSanitizer, which suggests that there is a use-after-free bug, while processing the example from snk6.ly; it also fails to process files as simple as `\score{c \layout{}}`, though providing arguably less helpful, but distinctly different output (attached as basic.txt).

I was not able to create such a minimal input file that would trigger the helpful trace.

Off-topic, I believe I transcribed the piece to sound pretty accurately,

but I have not seen the layout yet (because of the bug), so please don't tell me that it renders ugly.

Million thanks for such an awesome piece of software anyway :)

Please let me know if you need more info, or if the bug should be reported to one of the libraries instead.
