Dwarfdump cannot read 64-bit object with thread-local data
 
*I'm using dwarfdump and GCC on Debian (amd64). Dwarfdump cannot read debug info from 64-bit object file containing thread-local data. Error is DW_DLE_RELOC_SECTION_RELOC_TARGET_SIZE_UNKNOWN. Detail are below. Any Ideas?

You're much more likely to get a useful reply if you report a bug

This list is for development of Debian, not use of Debian packages for
development of other stuff.

Thanks.
