Description David Binderman 2005-05-23 17:14:35 EDT
Description of problem:

I just tried to compile package device-mapper-multipath-0.4.4-2.3 from
Redhat Fedora Core development tree with the most excellent Intel C
compiler. 
The compiler said

pgpolicies.c(246): remark #592: variable "pgp" is used before its value is set

The source code is

        struct pathgroup * pgp;

        if (VECTOR_SIZE(pgp->paths) < 0)
                return 0;

Clearly broken code.  Suggest initialise pgp before first use.
