Bug ID: 91027
Summary: [10 regression] SEGV in hash_table<odr_name_hasher,
false, xcallocator>::find_slot_with_hash
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Target: i386-pc-solaris2.11, sparc-sun-solaris2.11,
arm-unknown-linux-gnueabihf, i686-pc-linux-gnu,
x86_64-pc-linux-gnu
Between 20190626 (r272695) and 20190627 (r272755), a D LTO test regressed on
a couple of targets:
+FAIL: gdc.dg/lto/ltotests d_lto_ltotests_0.o-d_lto_ltotests_1.o link, -O0
-flto
(internal compiler error)
+FAIL: gdc.dg/lto/ltotests d_lto_ltotests_0.o-d_lto_ltotests_1.o link, -O0
-flto
-flto-partition=1to1 (internal compiler error)
+FAIL: gdc.dg/lto/ltotests d_lto_ltotests_0.o-d_lto_ltotests_1.o link, -O0
-flto
-flto-partition=none (internal compiler error)
+FAIL: gdc.dg/lto/ltotests d_lto_ltotests_0.o-d_lto_ltotests_1.o link, -O2
-flto (internal compiler error)
+FAIL: gdc.dg/lto/ltotests d_lto_ltotests_0.o-d_lto_ltotests_1.o link, -O2
-flto -flto-partition=1to1 (internal compiler error)
+FAIL: gdc.dg/lto/ltotests d_lto_ltotests_0.o-d_lto_ltotests_1.o link, -O2
-flto -flto-partition=none (internal compiler error)
I'm seeing it on 32 and 64-bit Solaris/SPARC and x86 alike, with Linux/i686 and
Linux/x86_64 reports as well.
