Hi,
I'm experiencing a problem with DDD when I ask to it to debug a program
which has to open a file and read some numbers.
This is a snapshot of the code:
REAL*8 RES,XMIN,XMAX,AUX,IR1,IR2,FOC,SX,SY,PSF
INTEGER NELE,NT
......
......
OPEN (UNIT=1,FILE='PIPPO.DAT')
READ (UNIT=1,FMT=100)
& XMIN,XMAX,SX,SY,FOC,PSF,IR1,IR2
100 FORMAT (
& E8.2/,
& E8.2/,
& E8.2/,
& E8.2/,
& E8.2/,
& E8.2/,
& E8.2/,
& E8.2
& )
CLOSE (UNIT=1)
When ddd reads these instructions gives the message:
(gdb) run
fmt: end of file
apparent state: unit 1 named PIPPO.DAT
last format: (E8.2,/,E8.2,/,E8.2,/,E8.2,/,E8.2,/,E8.2,/,E8.2,/,E8.2)
lately reading sequential formatted external IO
Program received signal SIGABRT, Aborted.
0x42029241 in kill () from /lib/i686/libc.so.6
(gdb)
PIPPO.DAT contains:
-.4
.4
12.5
12.5
25.0
24.5
1.0
1.0
My program works really well and I cannot understand why DDD stops
debugging.
I use g77 (gcc-g77-2.96-110) on a RedHat 7.3 to compile my programs:
g77 -g program_name -o prog.o
Can you help me?
Thank you
Massimo
