Bug #: 50468
Summary: ICE in force_type_die when compiling binutils with
-flto -O[12]
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: m...@use.net
Got this when building binutils-2.21.53.20110810 from source using g++-4.6.real
(Ubuntu/Linaro 4.6.1-9ubuntu3) or g++-4.7.0 20110914 on Ubuntu 11.10 amd64:
g++ -W -Wall -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -frandom-seed=ld-new
-g -flto -O2 -Wl,-Bsymbolic-functions -o ld-new main.o i386.o x86_64.o sparc.o
powerpc.o arm.o arm-reloc-property.o libgold.a ../libiberty/libiberty.a -ldl
-lz -lm
incremental.o (symbol from plugin): warning: memset used with constant zero
length parameter; this could be due to transposed parameters
In member function ‘__base_ctor ’:
lto1: internal compiler error: in force_type_die, at dwarf2out.c:21022
Interestingly, changing -O2 to -O1 introduces this variation:
incremental.o (symbol from plugin): warning: memset used with constant zero
length parameter; this could be due to transposed parameters
In file included from ../../gold/incremental.h:5152:0,
