Bug #: 51300
Summary: Internal error when using -flto with -O0 in the linker
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: miku...@artax.karlin.mff.cuni.cz
Host: hppa-linux-gnu
Target: hppa-linux-gnu
Build: hppa-linux-gnu
I get an internal error in gcc.
Steps to reproduce:
Use gcc 4.6.2 on Linux Debian 5 on PA-RISC
Get Links browser 2.4 from http://links.twibright.com/download/
Compile it with -flto so that individual modules are compiled with an
optimization, but the whole program is compiled without optimization:
CFLAGS="-O -flto" LDFLAGS="-O0" ./configure && make
The result is a gcc internal error:
gcc -O -flto -O0 -o links af_unix.o auth.o beos.o bfu.o block.o bookmarks.o
