Inconsistent javascript var values - Desktop vs Arm Kit - Qt 5.6

[Bob]

Hi all,

I'm working on a simple Ubuntu phone app with Qt Creator 3.5.1

I should mention I'm running ubuntu-sdk on Linux Mint 18 Sarah.Kernel version #37-Ubuntu SMP

After recently (9/7) updating the Build Kits (UbuntuSDK for armhf (GCC ubuntu-sdk-15.04-vivid)) && (UbuntuSDK for i386 (GCC ubuntu-sdk-15.04-vivid)) I am getting some bad javascript variable values.

When building and running the app with the Desktop Kit, I'm getting different javascript var values (which are incorrect) than when building and running on a phone with the armhf kit.

In the below function getAddress(type) the variables stip1, stip2, stip3, stip4 return inconsitent values.

Example output:

(Desktop)
input: 192.168.127.64/26
Start IP Address: 192.168.64.64

(Arm Kit on Phone)
input: 192.168.127.64/26
Start IP Address: 192.168.127.64 <-- correct

Thanks,

Bob
