I finally had a bit of time to look into this again. I concluded that the DOF data is invalid, or follows a format that's different from the one that GDB expected, and so added some code to detect and ignore... Attached is the patch with full explanation. Does it make sense to you? Yes, definitely, thanks for the fix! I will pass this information to the DTrace hackers. It would be nice to figure out why such an inconsistent DOF data is being generated in solarix-x86.
