I believe your elfutils was lacking the dwelf_relocation_debug_sections
replacement in strip.c while compiling.
Could you give a double check for whether the dwelf_relocation_debug_sections
is introduc

Got it. I have used GDB to make debuginfod stop at

$ cat /proc/$$/statm

Thanks Frank, I have debugged with rusage, but the difference between "during"
and "post" is not that obvious. I believe it's due to my small

I don't have many clue about how to debug/measure this memory fluctuation

What I did:
1) use GDB to check the call graph.

Asserts are heavily used across all elfutils libraries, and it's
impossible to implement the removing in one commit. So let's gradually
remove the asserts in the later coming commits.
