Summary: Disassembling create DWARF Errors
Product: binutils

compiled with binutils 2.34 and 2.35.1
Hello,
i have noticed that C++ programs compiled with binutils 2.35 or 2.35.1 often
produce DWARF errors when disassembling them. Whereby avr-gcc does not play a
role according to my tests. I have done comparison tests with binutils 2.34,
2.35 and 2.35.1 with avr-gcc 9.3, 10.1.0 and 10.2.0 respectively.
I attach two example files. What was compiled with which version is shown in
the file name.
In my opinion this concerns the obj-dump.exe of binutils 2.35 and 2.35.1. I can
disassemble both .elf files with the obj-dump.exe of binutils 2.34 without
errors. When I use the obj-dump.exe of 2.35 or 2.35.1 I get DWARF Errors. This
problem occurs more often when programming something with pointers. My feeling
tells me.
The C++ program compilation itself doesn't produce any errors, also no warnings
and the generated program works.
