Test is still failing , do you think this is an os issue ?

Don't know. Some more digging would need to be done in terms of whether or not the binary is properly SSE compiled (because XMM appears to be an SSE register according to a quick google search), and you should probably check with the binutils/gdb/redhat folks for more details about changes to the binutils, gdb, and/or libelf packages.

HTH,

Thanks, will look into this and update.

Thanks a lot for your time and effort :)
