Yes, I have seen that, but my dejagnu traces have this:
[...]
call_remote  download arm-sim current_symbols.txt current_symbols.txt
[...]
call_remote  load arm-sim ./abi_check {--check-verbose
current_symbols.txt baseline_symbols.txt} {}
[...]
call_remote  spawn arm-sim ./abi_check
[...]
spawning command  /XXX/qemu-wrapper.sh ./abi_check

so at some point the arguments are discarded.

In my site.exp, I have

       set target_list { "arm-sim" }
       global SIM
       set SIM "/XXX/qemu-wrapper.sh"

Not sure why I have this "arm-sim" here.
Maybe that's the reason for the problem I am seeing.

Yes, manually I get this:
[list of symbols etc...]
                ==== libstdc++-v3 check-abi Summary ====

# of added symbols:              136
# of missing symbols:            0
# of undesignated symbols:       2
# of incompatible symbols:       136

using: baseline_symbols.txt

*** EXIT code 1
