Generating JSON fails with duplicate key.

[Raphtaliyah]

I've run OOAnalyzer on a large program (9MB) using the multi step guide and it fails at the last step when it's generating the JSON results:

If I grep the results file for the duplicate key (0xa8b408) I get:

finalVFTable(0xa8b408, 0x4, 0x4, 0xa8b404, '.?AU?$error_info_injector@Vbad_lexical_cast@boost@@@exception_detail@boost@@').

I have the files from the previous steps and can send them in private if needed (the log file is 8.1GB tho and the first 3 steps took 48 hours to run and needed 155GB of RAM).

Can you share your results file? If so, that is the easiest way for us to see what is going on. You can email to eschwartz@cert.org if posting publicly is a concern.

It's a little odd that 0xa8b408 supposedly inherits from 0xa8ae80 at 0, and embeds 0x9e28cc at 0. But it's not impossible if 0xa8ae80 is a zero size class. And since 0xa8b408 is some boost exception class, that seems likely.

My concern was the name of the executable making this issue show up in search results but it should hopefully not this way! results.zip
