------- Comment #16 from jv244 at cam dot ac dot uk 2009-01-07 19:07 -------
I checked that current trunk (i.e. not graphite branch) still generates a
segfaulting executable with
FCFLAGS = -g -O2 -ffast-math -funroll-loops -ftree-vectorize -march=native
-ffree-form -fgraphite -fgraphite-identity -floop-block -floop-strip-mine
-floop-interchange
with a bt
Program received signal SIGSEGV, Segmentation fault.
