Indeed.

Must be an issue with dash ;-)

Compiling mksh from CVS gets me:

/usr/bin/ld: error in /home/tglase/dietlibc/bin-x86_64/dyn_stop.o(.eh_frame); no .eh_frame_hdr table will be created.

But the resulting binary passes its testsuite, modulo the
one expected-fail. This is on Debian sid.

Same with i386:
/usr/bin/ld: error in /home/tglase/dietlibc/bin-i386/dyn_stop.o(.eh_frame); no .eh_frame_hdr table will be created.
and no unexpected testsuite failures.

The bug in dietlibc CVS about ssize_t is still not fixed, by the way:
/home/tglase/mbsd/mksh/shf.c:458:3: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat=]
Fix is in the Debian dietlibc packaging.

Of course, there does seem to be something wrong here.


I can’t build dash at all:

But then, it’s not very good or portable, anyway. You’re better off
with mksh. (Disclaimer: I’m the mksh maintainer, and mksh has proven
to be a good toolchain testsuite…)
