Bug ID: 97918
Summary: ICE near htab_hash_string when LTO, -O & -g
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jengelh at inai dot de
Target Milestone: ---
Created attachment 49602
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49602&action=edit
Reproducer.
An ICE is observed on firefox-83 with gcc-10.2.1, persisting in git master du
jour too (d3f293348768667c07770e433ff00af51fee73a2).
I distilled the original cpp output from 298k to about 80k lines so far (x3.ii
attachment). The last two functions in that file ultimately trigger it all.
Perhaps the template parameter packs are causing this…
Taking away any one of -flto, -O or -g makes the compile succeed.

Yes, it looks very much related - the same "fix" works. Confirmed.

I'm reducing what looks like the same ICE for 19 hours already and am at 3.5MB

dwarf2: ICE with local class in unused function [PR97918]
Here, since we only mention bar<B>, we never emit debug information for it.
But we do emit debug information for H<J>::h, so we need to refer to the
debug info for bar<B>::J even though there is no bar<B>. We deal with this
sort of thing in dwarf2out with the limbo_die_list; parentless dies like J
get attached to the CU at EOF. But here, we were flushing the limbo list,
then generating the template argument DIE for H<J> that refers to J, which
adds J to the limbo list, too late to be flushed. So let's flush a little
later.

The new g++.dg/debug/localclass2.C test file you added is marked "target
c++11", but it seems I can only cause the crash with -std=c++17 or later
standards. Should the test file perhaps be amended?

--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For debug/ tests I guess it isn't really used, just documents that the testcase
is valid C++11 or later, because debug/ tests iterate over various debug
options rather than C++ standard options.

dwarf2: ICE with local class in unused function [PR97918]
Here, since we only mention bar<B>, we never emit debug information for it.
But we do emit debug information for H<J>::h, so we need to refer to the
debug info for bar<B>::J even though there is no bar<B>. We deal with this
sort of thing in dwarf2out with the limbo_die_list; parentless dies like J
get attached to the CU at EOF. But here, we were flushing the limbo list,
then generating the template argument DIE for H<J> that refers to J, which
adds J to the limbo list, too late to be flushed. So let's flush a little
later.
