[3.4b] slice2py gen hangs at "end of input"

joshmoore

For the same slice files we used with Ice 3.3.0 and 3.3.1, slice2py hangs on Mac 10.4. "Now at end of input" is printed with the "-d" flag, but the process does not exit (nor can it be cancelled before it gets to this point). slice2java exits cleanly for the same file.

The tarball contains all the slice files needed to build, but there are a lot of them.

Hang confirmed on Linux:

$ g++ -v

but "Now at end of input" is not reached. Last debug statement is:

Again, slice2java on the same file ends successfully.

Thanks for the report, we will look into it.

You can workaround the problem by removing line 1171 in API.ice, the "<<" in the comment is causing troubles to the parser. Thanks for the report this will definitely be fixed for the final release!

Cheers,
Benoit.
