It turns out the reason why my debugging version wasn't working is
because I had moved the directory to a new location. strace reveals
glob2 is trying to load these files just before it aborts because it
can't find texts.list.txt:
open("/home/jbw/.glob2/data/texts.list.txt", O_RDONLY) = -1 ENOENT (No such
file or directory)
open("./data/texts.list.txt", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/mnt/gentoo-portage/jbw/glob-debugging/glob2-0.8.22/share/glob2/data/texts.list.txt",
O_RDONLY) = -1 ENOENT (No such file or directory)
open("${datarootdir}/glob2/data/texts.list.txt", O_RDONLY) = -1 ENOENT (No
such file or directory)
open("/home/jbw/Desktop/software/glob-debugging/glob2-0.8.22/data/texts.list.txt",
O_RDONLY) = -1 ENOENT (No such file or directory)
The last one would have succeeded before I moved the directory.
I'm not sure why it is trying to load
"${datarootdir}/glob2/data/texts.list.txt". The ${datarootdir} here
should have been replaced at compile-time by a path.

directory).
The moral of the story:
Don't move your source directory after compiling it if you want to
reliably run the compiled program sitting in that directory.
