Bug ID: 37122
Summary: PVS-Studio Error: One counter for two loops
Product: Wine
Version: 1.7.22
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: -unknown
Assignee: wine-bugs at winehq.org
Reporter: lukebenes at hotmail.com
PVS-Studio identifies a V535 Error, one counter for two loops. The variable 'i'
is being used for this loop and for the outer loop. Check lines: 980, 1003.
iphlpapi_main.c 1003
...
for (i = 0; i < num_v6addrs; i++) //<==
{
...
for (i = 0; i < 8 && !done; i++) //<==
{
...
}
...
if (i < num_v6addrs - 1)
{
prefix->Next = (IP_ADAPTER_PREFIX *)ptr;
prefix = prefix->Next;
}
}
...
This fragment is suspicious: a nested loop is organized through the i variable
which is also used in the external loop.
