Segmentation Fault when the First Word is One Letter and Bolded

[jglowe]

I did a brief search and didn't see this issue reported anywhere, so here it goes.

I came across a segmentation fault when the score is bold and the first syllable is one letter long.

Below is an example of the error and the platform:

$ neofetch

I thought the issue might be that I didn't close the bold marker or placed it in the wrong place. Moving it around didn't fix it.

$ cat not_working1.gabc
%%
(c4)
<b>O(h) please(gh) help(h) me(g) main(h)tain(i)ers</b>(h.)
$ gregorio not_working1.gabc
Segmentation fault: 11
$

When I added another letter to the first word, it ran successfully.

$ cat working1.gabc
%%
<b>(c4)
Oh(h) please(gh) help(h) me(g) main(h)tain(i)ers(h.)
$ gregorio working1.gabc
$

Also moving the bold section after the first word/letter worked.

$ cat working2.gabc
%%
(c4)
O(h) <b>please(gh) help(h) me(g) main(h)tain(i)ers</b>(h.)
$ gregorio working2.gabc
$

I would appreciate any attention you can give to fixing this.

EDIT: can replicate. Previously I stated having problems with debug symbols, I was not compiling with --enable-debug.
