Thanks for your feedback.

Yes. Sorry for not being clear about the cause.

I found at least one another case:

% gdb -batch \~/gdb/tests/main  # or --exec=~/gdb/tests/main
~/gdb/tests/main: No such file or directory.

Whereas:
% gdb -batch --symbols=\~/gdb/tests/main
Succeeds.

Seems like gdb relies on the shell to expand its executable name.

As an alternative approach I can expand tilde in exec_file_attach
which is what symbol_file_add and core_file_command do.
