Subject: [Bug default/25439] New: namespace DIE added to duplicate chain list (--odr-mode=basic)
Date: Wed, 01 Jan 2020 00:00:00 -0000 [thread overview]
Message-ID: <bug-25439-11298@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=25439
Bug ID: 25439
Summary: namespace DIE added to duplicate chain list
(--odr-mode=basic)
Product: dwz
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: default
Assignee: nobody at sourceware dot org
Reporter: vries at gcc dot gnu.org
CC: dwz at sourceware dot org
Target Milestone: ---
Starting commit 62e4949 "Fix reference from PU to CU (--odr-mode=basic)", we
run into an abort in build_abbrevs_for_die with:
...
$ dwz -Lnone -lnone -o 1 Checker.so.debug --odr-mode=basic
...
This is a consequence of calling partition_found_dups with a die where
die->named_namespace == 1 during mark_singletons, the function added in the
offending commit.
This happens because a die:
...
(gdb) call dump_die (die)
4db7a86 O ffe1edf 0 imported_module
...
has a reference to a namespace:
...
(gdb) call dump_die (reft)
4c3e954 X 9a045343 0 llvm namespace
...
