tests failed on armv7

[juhp]

Not sure what is at fault but I note that some test-cases are failing when test building 0.5.1 in Fedora 24 development (Rawhide) for armv7hl:

This is with ghc-7.8.4.

Very strange. Have you tried building in the same
environment on non-armv7 machines?

Can you try building jgm/cmark (the C library cmark-hs
wraps) on your armv7 platform? You'd just need cmake,
and python3 to run the tests. It should be a
straightforward clone, make, make test.

Yes, it builds fine and make test runs okay.

(For the time being I have disabled the cmark-hs tests on armv7.)

[jgm]

OK, so that suggests to me that the cmake build procedure is
doing something that needs to be done on armv7, and that
isn't being done by the simple build ghc performs.

Edit: just to be clear - the cmark-hs tests still fail.

Note I am actually building the Haskell binding with my pkgconfig patch (thanks for the merge).
But this problem occurs in either case anyway. I suspect it could be either some issue with armv7 ghc or some endianness etc with the Haskell binding possibly? I haven't looked at the tests carefully so I am not sure what the failures are about exactly.

I can't reproduce anymore with 0.5.6 and bundled cmark in Fedora 28 Rawhide FWIW.
Not sure what changed, but the ghc version is now 8.0.2.

Neither with 0.5.5 and system cmark.
