Thanks for reporting the issues. We are collecting all issues reports, and at the end of this second test phase we investigate each one in order to fix the application. Can I ask you: it was just that work-units that report the problem or you get other work-units with the same error? Thank you very much ____________

For what I can see: - All the workunits running on computer ID 324 gave the same error. - That Gentoo kernel is rather old, around end of 2009 - I guess that is something related with linking/libraries etc. The output of the following commands should be useful to us readelf -d tngrid_expansion_v9_linux64 ldd -d -r tngrid_expansion_v9_linux64 - Do we distribute a statically builded executable? (I don't remember...) In this case adding -static to -static-libstdc++ could fix this... Otherwise I guess the only solution would be to build a static exe.

For what I can see:
- All the workunits running on computer ID 324 gave the same error.
- That Gentoo kernel is rather old, around end of 2009
- I guess that is something related with linking/libraries etc. The output of the following commands should be useful to us

readelf -d tngrid_expansion_v9_linux64 ldd -d -r tngrid_expansion_v9_linux64

- Do we distribute a statically builded executable? (I don't remember...) In this case adding -static to -static-libstdc++ could fix this... Otherwise I guess the only solution would be to build a static exe.

and the ldd command states not a dynamic executable
