Dear Maintainer,
A path expansion issue was firstly found while installing
python3-docutils/sid on armel/armhf/mips/mipsel, and has been reported
as bug 916225. Dash failed to expand the line for exe in
/usr/share/docutils/scripts/python3/* in python3-docutils' postinst
script, and failed the installation. With some more investigation into
this issue, I got following trace messages for dash:
Tracing started.
waitforjob(%0) called
pid 15608, evaltree(0xfffef918: 0, 1) called

expmeta begin loop
expmeta break loop: readdir error, errno 75
expmeta end loop
evalcommand arg: ls
evalcommand arg: /usr/share/vim/*
searchexec "ls" returns "/usr/bin/ls"
/usr/share/vim/* here shows such expansion failure doesn't only occur to
python3-docutils' postinst script, but also many other places. The errno
75 (EOVERFLOW) shows readdir() call may fail when one of the fields to
return cannot be represented correctly, so large file support should be
enabled whenever available.
