On an up-to-date Arch Linux system, not having jpegexiforient installed, feh segfaults if I open any jpeg and rotate it by pressing "<".

Here is the relevant GDB output:

feh WARNING: lossless rotate: Failed to exec jpegexiforient: No such file or directory
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff6701da8 in vfprintf () from /usr/lib/

Indeed, commenting out line 524 of imlib.c "vsnprintf(errstr, 1024, fmt, args);" prevents feh from crashing.

This bug is tracked on Arch Linux there:
Although I haven't had the time to go any further than the above yet.

Whoops. My bad, I forgot a printf argument so feh/imlib got sent into memory nirvana. This issue is fixed in feh 2.6.3.

Thanks a lot for looking into that so quickly!
