Hola:
Just to clarify a bit (I'm still having the issue):
I'm not getting a compilation error but a runtime problem.
When I run it I should get:
....
ref date Line: 20051020 count: 9289
ref date Line: count: 9290
9290 9290 19690102 20051020 20051019 20051018 20051017
Returned: 9290
but I'm getting:
....
ref date Line: 20051020 count: 9289
ref date Line: count: 9290
9290 9290 0 0 0 0 0
ERROR: Last Date reference (0) is before test's end date(19901231),
dates file=/usr/local/etc/SPX_DAILY_DATES.asc
i=9290 count=9290
Returned: 0
The file is a linux file, with one date per line as: 20051020
I the same result on Athlon 32 bits and Intel/Xeon 32/64 bit machines.

Hola:
I hope you can help me with this program:
- it works OK if I compile it with: g++ main2.cpp -o main2
- it fails if I compile it with: g++ -O2 main2.cpp -o main2
(but if I enable the comment inside the "try", then the
program works.)
This happens in my FC4 box with g++ --version g++ (GCC) 4.0.2
20051125 (Red Hat 4.0.2-8)
On my FC3 boxes and my RH7.3 boxes the -O2 is OK.
Any help is appreciated
Thanks.
