Bug ID: 90820
Summary: [10 regression] ICE in hashtab_chk_error, at
hash-table.h:1022
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Between 20190609 (r272089) and 20190610 (r272121), many C++ tests started to
ICE:
+FAIL: g++.dg/concepts/template-parm12.C -std=gnu++17 (internal compiler
error)
+FAIL: g++.dg/concepts/template-parm12.C -std=gnu++17 (test for excess errors)
+FAIL: g++.dg/cpp0x/pr54323.C -std=c++14 (internal compiler error)
+FAIL: g++.dg/cpp0x/pr54323.C -std=c++14 (test for excess errors)
+FAIL: g++.dg/cpp0x/pr54323.C -std=c++17 (internal compiler error)
+FAIL: g++.dg/cpp0x/pr54323.C -std=c++17 (test for excess errors)
and many many more. I'm seeing it on both Solaris/x86 and Solaris/SPARC, and
there
are gcc-testresults reports for Linux/i686 and Linux/x86_64, among others.
Excess errors:
hash table checking failed: equal operator returns true for a pair of values
with a different hash value

This is almost certainly due to
2019-06-10 Martin Liska <mli...@suse.cz>
* hash-map.h: Pass default value to hash_table ctor.
* hash-table.h: Add default value to call of a ctor.
