Which IDB are you using and how did you build the code?

First inspection in the error messages indicates that there is an error with unsupported dwarf attributes.
So we need also information about the OS, gcc version and Intel product you are using. Thanks. Hubert.

Hi, Thank You Hubert for Your Answer,

as Follows:
Operating System: openSUSE 11.4 M4 64 Bit Release
gcc 4.5.1
Intel C/C++ Studio XE 2011

Question: is its possible that a wrong gcc library the reason ?

best thanks
regards

Franz,

Yes, we saw issues with Dwarf4 attribues in gcc4.5 files under OpenSUSE 11. Currently, the Intel IDB Debugger stops at such unsupported dwarf attributes with an assertion failure. We will have a fix with the upcoming Intel Composer XE 2011 Update that ignores such non-essential attributes.

Do you have a small reproducer that shows the probem? If not, could you please provide the .debug_line dump (as file attachment) from the executable, e.g.

$ readelf -wl -x ".debug_line"

Hubert.

Franz,

Are you fine with waiting for the Intel Composer XE 2011 Update? Or with switching back to a gcc environment? (Using compiler option -gcc-name=430 allows to build your projects with gcc 4.3.x tools.)

Hubert.

Hi Hubert,

no problem , i can wait until the Intel Composer XE 0211 Update
thanks for the information against the -gcc compile switch,
works fine
