smooth() bug in (at least) version 8.5.1 [message #93939]

Hi,
I came across this bug and it's a "heavy" one, meaning that IDL crashes and you're thrown back out.

The crashing commands are (try at own risk!):
sm = smooth(indgen(512,511), 9, /edge_mirror)
sm = smooth(indgen(512,510), 9, /edge_mirror)

And just to be pedantic, I've tested a few other cases and these did NOT result in a crash:
sm = smooth(indgen(512,512), 9, /edge_mirror)
sm = smooth(indgen(511,511), 9, /edge_mirror)

It appears that smooth (stopped?) being able to smooth rectangular arrays.

By running the above from the command line I get the following error (for a couple of seconds on the command line terminal):
% Array has a corrupted descriptor: <no name>
% Execution halted at: $Main$

And my IDL version.
IDL> !version
{
"ARCH": "x86_64",
"OS": "Win32",
"OS_FAMILY": "Windows",
"OS_NAME": "Microsoft Windows",
"RELEASE": "8.5.1",
"BUILD_DATE": "Nov 14 2015",
"MEMORY_BITS": 64,
"FILE_OFFSET_BITS": 64
}

I others are brave enough, could you let me know if it crashes on other versions of IDL? Edge_mirror and _wrap have been added only in 8.1.

Cheers,
Helder
