Also tried with passing a &stats (of type rs_stats_t) instead of NULL, no workey either.

Try with fopen, it might be it!!

Compiled with
llvm-gcc test.c -lrsync -g3

touch old file
touch sigfile

./a.out

no errors

Confirmed: rs_sig_file in either arg seg faults. fopen does not. No confidence of actually working (needs more testing). Update: works on both gcc-4.2 and llvm-gcc

I see no errors and sigfile has something in it, that's my best guess for working state :P
