Follow-up Comment #3, bug #68552 (group groff): I reproduce it on Termux (32-bit arm) with clang 21.1.8.
Preparations:
1)
$ printf '.rr \\a\n' > in
2) Execute all environment variable commands from 'test-groff'.
First result: The issue comes from the object file src/roff/troff/input.o
being compiled with optimizations.
When I compile all object files with CFLAGS="-ggdb" and CXXFLAGS="-ggdb",
"./groff < in" prints a message 'error: expected identifier, got a
non-interpreted character node token; treated as missing', but no "Aborted".
When I compile all object files except src/roff/troff/input.o with
CFLAGS="-ggdb" and CXXFLAGS="-ggdb", and only src/roff/troff/input.o with
CFLAGS="-ggdb -O2" and CXXFLAGS="-ggdb -O2", "./groff < in" prints the same
message and then "groff: error: troff: Aborted".
Second result: stack trace from troff.
$ ./groff -V < in
troff -Tps | grops
Reproduce with 'troff' alone:
$ ./troff -Tps < in > out
./troff:<standard input>:1: error: expected identifier, got a non-interpreted
character node token; treated as missing
Aborted ./troff -Tps < in > out
The gdb session:
(gdb) run -Tps < in > out
(gdb) break abort
(gdb) break exit
(gdb) break _exit
(gdb) break error
(gdb) run -Tps < in > out

So it looks like __cxa_finalize() got into trouble because the memory
management data structures were inconsistent, leading to a misaligned pointer
somewhere.
Together with the first result, it smells a memory overrun error somewhere
(anywhere!). The best tool for diagnosing this is valgrind; ASAN is good but
only of limited usefulness.
So, if I were you, I would
1) try ASAN on that platform (Termux),
2) if not successful, run the entire 'troff' test suite under valgrind. Gnulib
documentation:
https://www.gnu.org/software/gnulib/manual/html_node/Running-self_002dtests-under-valgrind.html
.
3) If that is not enough to highlight a problem, extend the 'troff' test suite
with more test cases.
