I don't know how to compile/test AVR. Is it in the CompileFarm?
To anyone with more knowledge on AVR, any suggestion what could cause this? Is
there any special about signed/unsigned multiplication on AVR?

I don't know if it is in the Compile Farm, or not. But I can test for you.
Note that AVR has 8-bit chars, 16-bit ints and pointers, 32-bit longs.

I need a way to debug this. I have no idea what the issue is.

That doesn't ring a bell.
Anyway, this is not a regression. My patch added the testcase. The bogus
warning was there already.

Just a guess, given the above: for unsigned char b, b*1000 is signed integer
and it may overflow, so probably this is causing the warning. Perhaps we should
only run this testcase with int32plus targets.

This is what happened on bug #37663 recently.

Eric,
Could you modify the testcase to use 100 instead of 1000 and run it under AVR?

The test is successful if the 1000 is changed to 100.
