Alright, I think I'm hitting my limits here.
Versions 1.44, 1.44.2, and 1.44.3 all fail in a similar way:

Version 1.44.4 is the first one I was able to build, using the packaging
from debian/1.44.6-1 (first 1.44.x version that was packaged and that's
also known to be buggy).
This would suggest the regression in caused by something in here:
Overview of changes in 1.44.4
=============================
- Add an insert-hyphens attribute
- Reinstate the return type of pango_fc_font_lock_face
- Fix a problem with ellipses getting the wrong font
- fc: Improve filtering by font format
- Re-add PangoFcFont to public headers
- Install PangoFc and PangoOT introspection files
- Fix ink rectangles to have positive height
- Fix mark positioning
- Switch to using harfbuzz for metrics
Overview of changes in 1.44.3
=============================
- Install pango-ot headers
- Make subpixel positioning optional
- fc: Ignore fonts with unsupported formats
Overview of changes in 1.44.2
=============================
- Disable ligatures when letterspacing
- Set design coords on hb_font_t
- Expose more font options in pango-view
- OS X: Make 'system-ui' font work
- Keep deprecated pango-fc apis in headers
- Make hex boxes work, always
- introspection: Various build fixes
- introspection: Add PangoPT, PangoFT2 namespaces
- layout: Make the new line-spacing opt-in
Overview of changes in 1.44.1
=============================
- Fix a crash with allow_break attributes
- Fix Emoji spacing
- Fix up includes and pkg-config requires
- Correct some cases for hyphen insertion
Overview of changes in 1.44.0
=============================
- Use harfbuzz for shaping on all platforms
- Stop using freetype for font loading; this
drops support for type1 and bitmap fonts
- Add a getter for hb_font_t
- Make PangoCoverage a GObject
- Add a pango_tailor_break api
- font metrics: Add line height
- layout: Support line spacing
- layout: Draw hyphens for line breaks
- Add an attribute to suppress line breaking
- cairo: Don't render hex boxes for space
- Add an attribute to show invisible characters
- Stop quantizing glyph positions
- Add tests for itemization and line breaking
- Remove language and shape engine remnants
- Rename meson options: gtk_doc, introspection
- Require GLib 2.59.2
- Require Harfbuzz 2.0
but as mentioned initially, I don't think I can go deeper in my “blind”
(I don't know anything about pango or rendering in general) bisection of
pango1.0.
At first, the upstream/fix-deadlocks* branches sounded promising,
especially with such a commit message:
Fix hangs that people have observed
but those are regression fixes in the 1.48.x series, and a quick look
around in previous versions doesn't seem to show similar initialization
routines, so someone else is likely happening in 1.44.x…
Help/pointers appreciated.
