** [issues:#5964] Multi_measure_rest_engraver segfaults when its context
doesn’t include Staff_symbol_engraver.**
**Status:** Accepted
**Labels:** Regression
**Created:** Wed May 06, 2020 10:47 PM UTC by Valentin Villenave
**Last Updated:** Wed May 06, 2020 10:59 PM UTC
**Owner:** nobody
This used to work as recently as 2.20.0, and it no longer does:
~~~~
\version 2.21.1
\layout {
\context {
\type Engraver_group
\name GlobalRests
%\consists Staff_symbol_engraver
%\omit StaffSymbol
\consists Multi_measure_rest_engraver
}
\context {
\Score
\accepts GlobalRests
}
}
\score {
\new GlobalRests { R1 }
}
~~~~
Uncommenting the Staff_symbol_engraver prevents the segfault from happening.
Here’s what gdb has to say:
~~~
Program received signal SIGSEGV, Segmentation fault.
Grob::internal_get_property (this=this@entry=0x0, sym=0x7fffe98e1ea0) at
grob-property.cc:162
162 SCM val = get_property_data (this, sym);
