Getting all the debuginfo packages that are needed to analyze a core can be quite a
challenge.
Did you install all the dependent debuginfo packages?
debuginfo-install hedgewars
Even then there might have some missing.
Once all the dependent debuginfos are installed you could look at the core
to try and find out what's missing with (coredump is the core here):
eu-unstrip -n --core coredump |\
gawk '{TMP=$2; $1=$2=""; print "/usr/lib/debug/.build-id/" substr(TMP,0,2) "/" substr(TMP,3,38) $0}'
Using the output from above dnf can be used to work out what's missing
with somewhat less guess work than usual, eg.
dnf provides /usr/lib/debug/.build-id/be/b9dc6f92875b3faa920e09241e8ab98b0e7c27
etc.
