Still not much progress. Under valgrind ZSTD_decompressStream does indeed return an error: ZSTD_decompressStream: -20 (1) Corrupted block detected Will have to trace that with/without valgrind to figure out if it is a bug in valgrind or some memory operation that behaves different under valgrind that causes an issue in ZSTD_decompressStream.

[Bug tools/28873] New: Implement eu-readelf -D
https://sourceware.org/bugzilla/show_bug.cgi?id=28873
Bug ID: 28873
Summary: Implement eu-readelf -D
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org
Reporter: dichen at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
Currently, eu-readelf is using section headers (in readelf.c:handle_symtab(),
it calls gelf_getshdr() for fetching section headers and get related info like
section size, type, etc) to find the symbol information and print them.
This task will add new options to eu-readelf (-D and --use-dynamic).
And this task aims for printing the symbols by lookup through the program
headers
and the dynamic table. PT_DYNAMIC->DT_* for DT_{GNU_,}HASH, DT_SYMTAB,
DT_STRSZ,
DT_VERNEED, DT_VERSYM(for version information), etc.
