Hi Dmitry,

If you run your ELF binary through "readelf -w" does it report any
problems with the debug information ?

Yes, a lot of. Like this:
readelf: Warning: There is a hole [0xab1ea0 - 0xab2551] in .debug_loc section.
readelf: Warning: There is an overlap [0xab25ab - 0xab1ea0] in .debug_loc sectio

So the DWARF information in the ELF file is broken ? That would explain why this problem has not been encountered by other people.

Without a test case and a procedure to follow to reproduce the bug, I
really do not think that we are going to be able to solve this
problem.  Are you sure that you cannot provide us with an ELF file ?
You could always zero out the proprietary information first before
uploading it.

I'm afraid I will need to remove whole debug info in order to remove this
proprietary info.

How can the debug info be proprietary ? Maybe some of the symbol names, but you can always change those.
