Bug#838425: casacore: FTBFS on armel, armhf, mips, and hppa: tConvert assertion failure

[Aaron M. Ucko]

Source: casacore
Version: 2.1.0-2
Severity: important
Justification: fails to build from source

Builds of casacore on armel, armhf, and mips, and the non-release
architecture hppa all encountered identical assertion failures in test
447 (tConvert):

  Traceback (most recent call last):
    File "tConvert.py", line 189, in <module>
      dotest(t)
    File "tConvert.py", line 65, in dotest
      print t.testvh (a);
  RuntimeError: (/«PKGBUILDDIR»/casacore/python/Converters/PycArrayComCC.h : 
310) Failed AlwaysAssert PyArray_ISCONTIGUOUS(po) && PyArray_ISALIGNED(po) && 
!PyArray_ISBYTESWAPPED(po)
  FAIL (execution failure): ./tConvert

On most of these architectures, there was at least one other test
failure, which I'll report separately if I haven't already.

Could you please take a look?

Thanks!
