[...] Thanks a lot for taking the time to investigate the issue and for providing the fontconfig patch! I've been away from home and couldn't reply earlier. As the issue has now been solved xterm-wise, just a few remarks: >> Reading symbols from /usr/bin/xterm...Reading symbols from >> /usr/lib/debug/.build-id/b8/d462fb6f4969a6a228262ceff981af02a1a4d5.debug...done. >> done. >> (gdb) run -fa 'Noto Mono' > > fwiw, my Debian/testing machine has these fonts (with "noto" in their names): > > ii fonts-noto 20181130-1 > all metapackage to pull in all Noto fonts > ii fonts-noto-cjk 1:20170601+repack1-3 > all "No Tofu" font families with large Unicode coverage > (CJK regular and bold) > ii fonts-noto-color-emoji 0~20180810-1 > all color emoji font from Google > ii fonts-noto-hinted 20181130-1 > all "No Tofu" font families with large Unicode coverage > (hinted) > ii fonts-noto-mono 20181130-1 > all "No Tofu" monospaced font family with large Unicode > coverage > ii fonts-noto-unhinted 20181130-1 > all "No Tofu" font families with large Unicode coverage > (unhinted) Exactly the same on my system. fonts-noto-color-emoji was only recently installed via a dependency at the same time as xterm was upgraded from 337 to 338. It turns out that simply removing the package fonts-noto-color-emoji eliminates the issue! So that's probably the best workaround right now for anyone with the same problem, until your patch is incorporated into fontconfig.

For the record, no, the trace had been made with the provided xterm-dbgsym and libfontconfig1-dbgsym packages. Best Alex
