Hi,

It sounds like an unexpected exception is being thrown in the Slice::Contained constructor and this is causing a crash because of missing __setNoDelete calls in the constructor (see this FAQ for the reason).

Could you wrap the constructor code (in cpp/src/Slice/Parser.cpp line 459) with the following and try again after recompiling the Slice library:

    __setNoDelete(true);
    ...
    __setNoDelete(false);

This should allow the exception to propagate and be displayed by the parser and hopefully give you more clues on the reason why the parsing fails.

Cheers,
Benoit.

Inspecting IceUtil/Shared.h seems to indicate that

70: assert(_ref > 0);

is failing. This is unaffected by the value of _noDelete.

I'm trying a code change to comment out the assert(), and return instead. However, I'm concerned this may be hiding a deeper problem...

Hi,

Yes, this assert doesn't look good. Which gcc version do you use?

Did you try to translate the py/test/Slice/keyword/Key.ice manually with slice2py? Does it work? You could also try to run other tests or some of the demos.

Also, which python version do you use on your platform? Did you build it yourself?

Cheers,
Benoit.

Benoit,

Thanks for the hint - I have multiple versions of Python on the system, and had configured the wrong one.

All 19 tests now pass!

Thanks, everyone, for the patient help.

Philip
