[Openexr-devel] pyilmbase - Iex_2_2::InvalidFpOpExc crash

[Michał Frątczak]

So I managed to build pyilmbase (CentOS 6.5 + Red Hat DTS 2.1 (g++ v4.8.2)), and I run tests from file pyImathTest.py

All of them pass except for testFpExceptions() which crashes with following error:

terminate called after throwing an instance of 'Iex_2_2::InvalidFpOpExc'
  what():  Invalid floating-point operation.
Aborted (core dumped)

The crash happend on line 8038:

    f = sqrt (-1)

It will pass if I remove preceding code fragment, starting at line 8023:

    # The overflow exception is not masked properly on Windows -- see
    # Platform/PlatformFpu.cpp and note the non-implementation of
    # setFpExceptions().
    #
    if sys.platform != 'win32' and sys.platform != 'darwin':
        try:
            v = V3d (1e200, 1e200, 1e200)
            v = v * v * v
            print v
        except iex.MathExc:
            pass
        else:
            assert 0

Is this smth I should worry about? Any hints appreciated.

thanks,
