I am actually seeing this problem with the aermod, air, capacita, doduc,
fatigue, gas_dyn, induct, linpk, mdbx, nf, protein, rnflow, test_fpu and tfft
benchmarks with...
-O2 -fgraphite-identity -floop-strip-mine
The ICEs are...
tfft.f90: In function tfft:
tfft.f90:3:0: internal compiler error: Floating point exception
rnflow.f90: In function invima:
rnflow.f90:2878:0: internal compiler error: Floating point exception
test_fpu.f90: In function gauss:
test_fpu.f90:89:0: internal compiler error: Floating point exception
protein.f90: In function superficie_proteina:
protein.f90:1585:0: internal compiler error: Floating point exception
nf.f90: In function trisolve:
nf.f90:227:0: internal compiler error: Floating point exception
mdbx.f90: In function cbuild:
mdbx.f90:1425:0: internal compiler error: Floating point exception
linpk.f90: In function matgen:
linpk.f90:44:0: internal compiler error: Floating point exception
induct.f90: In function mutual_ind_cir_cir_coils:
induct.f90:777:0: internal compiler error: Floating point exception
gas_dyn.f90: In function cortesa:
gas_dyn.f90:1791:0: internal compiler error: Floating point exception
fatigue.f90: In function iztaccihuatl:
fatigue.f90:1265:0: internal compiler error: Floating point exception
doduc.f90: In function s00017:
doduc.f90:1480:0: internal compiler error: Floating point exception
capacita.f90: In function capacitance:
capacita.f90:573:0: internal compiler error: Floating point exception
air.f90: In function state:
air.f90:1034:0: internal compiler error: Floating point exception
aermod.f90: In function chk_endyr:
aermod.f90:5620:0: internal compiler error: Floating point exception
In case it helps reproduce the problem on x86_64 linux, on
x86_64-apple-darwin10...
