[Bug-gsl] gsl-1.12 make check failure with gcc-4.4.1

I am building a recent Linux From Scratch system based on the gcc-4.4.1, glibc-2.10.1 and binutils-2.19.1 toolchain. On building gsl-1.12 I noticed that it compiles/builds OK but shows the following failure on make check

make[2]: Entering directory `/home/drososa/gsl-1.12/integration'
FAIL: qawc(f459) elist (1.83292424966307774e-15 observed vs 1.83308294820715351e-15 expected) [744]
FAIL: test

The error disappears when I compile with CFLAGS="-O" indicating an overaggressive optimization (perhaps? on the side of the gcc-4.4.1 compiler). I observed a similar pattern in the past with gcc-4.3.2 which was fixed with gcc-4.3.3 (the one I am using now for my everyday work).

If anyone has a Linux system using the same compiler please verify the above. If the FAIL persists someone should inform the gcc people. I would like to upgrade to a more recent gcc provided I can still do my work (based heavily on gsl).

If more info is required please contact me directly.
