[Bug debug/50279] [4.7 Regression] ICE while building the go front-end with LTO enabled
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50279 --- Comment #9 from Peter Foley jpfoley2 at verizon dot net 2011-10-10 20:34:01 UTC --- (In reply to comment #8) (In reply to comment #7) I've attached a reduced testcase that reproduces the ICE with the commandline g++ -nostdlib -flto -g test.i This test case doesn't trigger the ICE on x86_64-apple-darwin11... howarth% g++-fsf-4.7 -nostdlib -flto -g -c test.ii howarth% Note on darwin '-c' is required, else the test case fails with... howarth% g++-fsf-4.7 -nostdlib -flto -g test.ii ld: warning: symbol dyld_stub_binder not found, normally in libSystem.dylib ld: entry point (start) undefined. Usually in crt1.o for architecture x86_64 collect2: error: ld returned 1 exit status -c prevents the test case from triggering the ICE on x86_64-pc-linux-gnu for me as well. Try removing -nostdlib from the commandline.
