I get the same error with the file I sent you in issue #22, but I thought it had something to do with the way the file is formatted. After reading the file using normal readelf, Using:
$ readelf --debug-dump=decodedline uvision/O0/obj/UserManualExample.axf
I get:
Decoded dump of debug contents of section .debug_line:

I am pretty sure the error comes from having two different CUs which are both from main.c. Do you think this is it? This is the standard output for armcc, so not sure what can be done from the compiling/elf side. Please let me know your thoughts. Roberto
By the way. using the readelf.py script I get the following:
...
system_SLE90.c 291 0x100061a8
system_SLE90.c 295 0x100061aa

I managed to fix the code by checking that dwarfinfo.line_program_for_CU actually returns something:
lineprog = dwarfinfo.line_program_for_CU(CU)
if lineprog != None:
do stuff with get_entries
I guess this could be added to the examples (decode_address) and the readelf.py script. Cheers!
