Description David Binderman 2005-03-09 09:14:27 EST

Description of problem:

I just tried to compile device-mapper-multipath-0.4.2-1.0 from Redhat
Fedora Core development tree with the Intel C compiler.

The compiler said

main.c(650): remark #592: variable "mode" is used before its value is set

The source code is

                if (mkdir(CALLOUT_DIR, mode) < 0) {

Suggest init local variable mode before first use.

>is the following enough to calm ICC ?

I haven't tested it, but a visual inspection suggests it will.

Comment 3 Lars Marowsky-Bree 2005-04-21 07:08:47 EDT

This is fixed in 0.4.3 and up. Can this bug be resolved now?
