[Debian-med-packaging] Bug#798715: opensurgsim: FTBFS on s390x and ppc64: Assertion failed: nodeId < m_numNodes

[Aaron M. Ucko]

Source: opensurgsim
Version: 0.6.0-2
Severity: important
Justification: fails to build from source

Builds of opensurgsim for 64-bit big-endian architectures have been
failing with test suite errors along the lines of

C++ exception with description "09.11 00:49:41 default CRITICAL *** Assertion failed: nodeId < m_numNodes ***
    in ???
    at /«PKGBUILDDIR»/SurgSim/Math/OdeState.cpp:128
Invalid nodeId 1670742278144 number of nodes is 391" thrown in the test body.

In this example, 1670742278144 is 389 << 32, so I suspect that
something incorrectly expects the low-order bits of 64-bit integers to
come before the high-order ones in memory.

Could you please take a look?

Thanks!
