Comment 1 for bug 73571

Correction:
It only segfaults for me if I combine LC_ALL="??_??.UTF-8" with LANGUAGE=sv.

$ LC_ALL=en_US.UTF-8 LANGUAGE=sv dd if=/dev/zero of=/dev/null bs=1 count=2
2+0 records in
2+0 records out
Segmentation fault

$ LC_ALL=C LANGUAGE=sv dd if=/dev/zero of=/dev/null bs=1 count=2 2+0 records in
2+0 records out

$ LC_ALL=en_US.UTF-8 LANGUAGE=en dd if=/dev/zero of=/dev/null bs=1 count=2

Copying a single byte also works:

$ LC_ALL=en_US.UTF-8 LANGUAGE=sv dd if=/dev/zero of=/dev/null bs=1 count=1
