            Bug ID: 19523
           Summary: objdump: does not support compressed debug sections
           Product: binutils
           Version: 2.26
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: doko at debian dot org
  Target Milestone: ---

[forwarded from https://bugs.debian.org/812089]

objdump does not seem to support compressed debug symbols. As we now
have -dbgsym packages in Debian which ship such files, this is likely to
byte more people in the future.

Test case:

$ cat <EOF >>test.c
int main(int argc, char **argv)
{
        return 42;
}
EOF
$ gcc -g -o test test.c
$ objcopy --only-keep-debug --compress-debug-sections test test.debug
$ strip --remove-section=.comment --remove-section=.note test
$ objcopy --add-gnu-debuglink=test.debug test
$ objdump --disassemble --line-numbers test >/dev/null
