I am using the cyclone demo and have 4 ws2812b 144 led strips on D2-D5 on a genuine arduino nano.
The code in question looks like
LEDS.addLeds<WS2812,5,RGB>(leds,NUM_LEDS);
LEDS.addLeds<WS2812,4,RGB>(leds,NUM_LEDS);
LEDS.addLeds<WS2812,3,RGB>(leds,NUM_LEDS);
LEDS.addLeds<WS2812,2,RGB>(leds,NUM_LEDS);

This causes a compile error.
FastLED version 3.002.001

lto-wrapper.exe: fatal error: C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avr-gcc returned 1 exit status

compilation terminated.

c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/5.4.0/../../../../avr/bin/ld.exe: error: lto-wrapper failed

collect2.exe: error: ld returned 1 exit status

exit status 1
Error compiling for board Arduino Nano.

Yet when I use 5,4,3,6 it compiles.
The problem is the nano is already epoxied in place and I really need to use D2-D5 if possible.

Thanks in advance.

This looks like it is most likely a bug in Arduino/the compiler Arduino uses - what version of Arduino are you using?

In my app if I have 5,4,3, and 2 OR 5,4,3 and 6 I get

lto-wrapper.exe: fatal error: C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avr-gcc returned 1 exit status

compilation terminated.

c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/5.4.0/../../../../avr/bin/ld.exe: error: lto-wrapper failed

Can you please copy/paste the entire build log into gist.github.com and post the link here. I want to see if there’s any other messages that hint at what is going on.

It looks like you might be hitting this issue in Arduino - arduino/Arduino#7949

There's some comments here - https://forum.arduino.cc/index.php?topic=568731.0 - that have workaround suggestions:

This bug is specific to the 5.4.0-atmel3.6.1-arduino2 version of avr-gcc used by Arduino AVR Boards 1.6.22 and newer. It has been reported here:
arduino/Arduino#7949

Here's the traditional workaround:
Tools > Board > Boards Manager
Wait for downloads to finish.
When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
Click "Install".
Wait for installation to finish.
Click "Close".

See if that helps.
