Sorry for the extra emails.
With all the engravers removed, as previously stated, it proceeds to
"Preprocessing graphical elements..." before giving code -1073741819.
The following engravers, when individually enabled (i.e., commenting
out the single "\remove" line), cause the problem to occur during
"Interpreting music..." prior to "Preprocessing graphical objects...":
Score:
System_start_delimiter_engraver
Spacing_engraver
Vertical_align_engraver
Staff
Ledger_line_engraver
Staff_symbol_engraver
Figured_bass_engraver
None of the engravers in Voice cause the problem, even when they are
all enabled.
If I enable all the engravers under Staff except the 3 that cause the
problem individually, I still get -1073741819.
That's all the testing I can do tonight, as it's late here. I'd be
happy to continue tomorrow.
