Hi Sasha,


I received this feedback from the user:

   Hi Jim

   I was able to load this module and run the job, but I still got

   osscollect:
   
/projects/OpenSpeedShop/jgalaro/openspeedshop-externals/BUILD/serrano-login1/dyninst-20180514frame/parseAPI/src/SymtabCodeSource.C:559:
   void Dyninst::ParseAPI::SymtabCodeSource::init_try_blocks():
   Assertion `!"WARNING: overlapping try blocks\n"' failed.


So, the fix must be for a different issue, unfortunately.
Do you have any ideas for next steps?

Thanks,
Jim G

Hi Jim,

we are trying to fix this issue. There is already a fix related to tryblocks but it's not in the master branch, nor it has been tested yet.

Meanwhile, you may want to merge this commit locally and see if itfixes your problem. It's in the branch sasha/fix-eh-frame-parse.

I will test it and possibly merge to master but without further data Ican't tell if it fixed your issue.


Let us know if you have any success.


Regards,

Sasha

Hi Jim,

In theory, try blocks should not overlap because otherwise how we knowwhich catch block to handle the exception happened at the overlappingaddress.

So, it is more likely that there is a problem with the eh_frameparsing, which leads to wrong try block ranges.


For debugging, can you ask the user to run

objdump --dwarf=frames-interp PATH_TO_THE_TARGET

and sends us the output?

This command should output the correct exception handling information.We can then determine whether there is indeed overlapping try blocksor the parsing of try blocks is wrong.


Thanks,

    We have an abort that is showing a

    //The code is protected, so we don't have source code access or

    Can anyone shed any light on what might cause overlapping try
    block assertion?
    This OSS version was built with a Nov 28, 2107 version of Dyninst.

    Thanks,
