The mapping between addresses and code locations is invalid in object files compiled for AVR targets that addresses code above 64K. This seems like a "rollover" bug because addresses immediately above 64K have values near 0.
To reproduce this bug, generate a source file that uses more than 64K of program memory and try to parse the .debug_line section using libdwarf or by implementing the state machine described in section 6.2 of "DWARF Debugging Information Format" revision 2.0.0 This is probably a side-effect of the AVR usually only addressing 64K of program memory. http://reality.sgi.com/davea/ http://dwarf.freestandards.org/modules.php?name=Content&pa=showpage&pid=6 -- Summary: Overflowed address in dwarf debug line information Product: gcc Version: 3.4.1 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tsandnes at atmel dot com CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: mingw32 GCC host triplet: 386 GCC target triplet: AVR http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19087
