Target: i686-pc-linux-gnu
Configured with: ../gcc/configure --prefix=/usr/local/gcc-43
--program-suffix=-43 --enable-threads=posix --enable-languages=c,c++,fortran
Thread model: posix
gcc version 4.3.0 20070517 (experimental)
gfortran-43 -save-temps -c test.for
test.for: In function xyz:
test.for:1: internal compiler error: Illegal instruction
"-save-temps" does not return any meaningful output.
A simple oiece of code that reproduces this problem follows below. Delete the
IF-statement and there's no longer any ICE.
SUBROUTINE XYZ( XY, KPT )
C
IMPLICIT DOUBLE PRECISION ( A - H, O - Z ), INTEGER ( I - N )
C
DIMENSION XY(*)
C
I = 0
DO 6000 JP = 1, 10
ABC = XY( JP )
IF ( ABC .GT. 0.0D0 ) THEN
C
DO 300 KK = 1, KPT
I = I + 1
300 CONTINUE
C
END IF
C
6000 CONTINUE
C
RETURN
END
