I apologise. I omitted an essential part of the first unpack template (the repeat *). Please try substituting this:

my @matrix = map[ unpack 'C*', $_ ], unpack '(a' . NCOLS . ')*', $buff +er;
The template has become: '(a3954)*' which tells unpack to split the buffer into as many 3954-byte chunks as are available.

In the absence of evidence, opinion is indistinguishable from prejudice.

[1nickt]: Quick survey: has anyone used or even heard of autobox?
[Corion]: thezip: I would expect some (fancier?) numeric formatting to fail from these test failures
[1nickt]: ( Sometimes when idle I browse remote corners of the code repo at $work ... usually this yields knowledge of projects to decline and coworkers to avoid ... )
[LanX]: sure
[Corion]: 1nickt: Finding autobox in production would give me pause, yes
[LanX]: efficient survey
[MidLifeXis]: And under MINGW64_NT-6.1 MYHOST 2.6.0(0.304/5/3) 2016-09-09 09:46 x86_64 Msys there seem to be issues with escapes in external build tool calls.
[Corion]: I mean, it's a technical feat it achieves, but... why? ;)
[MidLifeXis]: And it also has the 0.14 version of the tarball in its manifest.
[LanX]: avoiding unreadable brackets
