Summary and Info:

Git commit ea3c478 reverted commit 3e4d2c3 “libalpm: compare pkgname with strcoll”. Now Pacman compares package names with “strcmp” instead of “strcoll”. However the reverted commit seems closely tied to the commit immediately following it: d7dccd5 “makepkg: remove unnecessary use of sort”. So I suggest reverting the second commit to restore the “sort” call.

An alternative might be to set LC_COLLATE=C for the two “comm” calls.

Steps to Reproduce:

* Build a package with the “makepkg --rmdeps” option, using LC_COLLATE=en_US.UTF-8 or similar
* Presumably if you have enough hyphenated packages installed it will trigger the fault. For example I have the following packages installed, but “avrdude” should come before “avr-gdb” according to the “sort” and “comm” commands.

avahi
avr-gdb
avr-libc
avrdude
babl
