I have a program I was testing with gdb. I was trying to figure out
why c.rmonths was always zero when it should have been 6. Stepped
through using the gdb n command. Here is the output:
(gdb)
215 c.rmonths = (edate - tdate) / toMONTHS;
(gdb)
223 c.dial_in = u.dial_in[0];
(gdb)
224 c.dsl = u.dsl[0];
(gdb) p c.rmonths
$1 = 0
(gdb) p c
$2 = {fa = 0, pwp = 0, disp_email = 0, imonths = 0, rmonths = 6,
type = 73 'I', cd = 0 '\0', dial_in = 82 'R', dsl = 0 '\0',
dsl_kit = 0 '\0', ip = 0 '\0', domain = 0 '\0', n_domain = 0 '\0',
renewal = 89 'Y', program = "I\000\000"}
(gdb) p c->rmonths
$3 = 6
(gdb) p c.rmonths
$4 = 6
Notice, the first time i print it its zero. The second time its 6.
What gives here? I have seen this before but couldn't pin it down.
The program is not compiled with any optimization. It is in a shared
library though.
It is hard to tell without the code you used. I would put some printf's in
the code and see what and when that variable gets set to in actual running
code.
