Comment #12 on issue 1732 by address@hidden: occasional segfault  
when compiling input/regression/midi/key-initial.ly

You might want to add the suppressions from the attached file, which  
filters practically all spurious warnings triggered in guile's garbace  
collection...

There are, however, two relevant warnings in that log file, which might  
help pinpoint the problem:
