When gsl is built with FSF gcc 4.6 at -O1, the failure in the gsl testsuite
becomes a segfault...
Making check in cheb
make test
gcc-fsf-4.6 -DHAVE_CONFIG_H -I. -I.. -I.. -O1 -MT test.o -MD -MP -MF
.deps/test.Tpo -c -o test.o test.c
mv -f .deps/test.Tpo .deps/test.Po
/bin/sh ../libtool --tag=CC --mode=link gcc-fsf-4.6 -O1 -o test test.o
libgslcheb.la ../ieee-utils/libgslieeeutils.la ../test/libgsltest.la
../sys/libgslsys.la ../err/libgslerr.la ../utils/libutils.la -lm
libtool: link: gcc-fsf-4.6 -O1 -o test test.o ./.libs/libgslcheb.a
../ieee-utils/.libs/libgslieeeutils.a ../test/.libs/libgsltest.a
../sys/.libs/libgslsys.a ../err/.libs/libgslerr.a ../utils/.libs/libutils.a -lm
make check-TESTS
/bin/sh: line 1: 4837 Segmentation fault ${dir}$tst
FAIL: test
whereas the gsl built with FSF gcc 4.5.2 at -O1 passes its make check fine.
