Bip

This probably leaks some memory.

1. strace -f -e open,access src/bip -f /home/renzokuken/bip.conf.test -n -s /var/lib/tiret_qsdf
   access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
   access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)
   open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
   access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
   open("/usr/lib/x86_64-linux-gnu/libssl.so.1.0.0", O_RDONLY|O_CLOEXEC) = 3

I re-run right away:

Everything is fine if the path passed to -f doesn't contain any _ or -
