Bug ID: 61291
Summary: libixion-0.5.0 unable to find boost thread library as
lto1 crashes with segfault
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: steffen at hauihau dot de
The configure script of libixion tries to find the correct name of the boost
thread library, but each try failes with a segmentation fault in lto1.
Here is a snippet from config.log:

It even segfaults with non-existing libraries like boost_thread-mt-1_55.
I've stripped it down to the usage of "-Os" together with "-flto". Here is a
minimal snippet of code which produces the error:
#include <boost/thread.hpp>
int
main ()
{
boost::thread t; boost::mutex m;
;
return 0;
}
I've compiled it this way:
x86_64-pc-linux-gnu-g++ -c -flto=5 -Os boost_gcc_lto_segfault.cpp
x86_64-pc-linux-gnu-g++ -o boost_gcc_lto_segfault -flto=5 -fuse-linker-plugin
boost_gcc_lto_segfault.o -lboost_thread-mt -lboost_system-mt
Please let me know if you need further information.
This is the output of "gcc -v":
