gcc compiler problem

Hi,
I have a code which I have compiled on solaris 2.5.1 (gcc 2.7.2.2)and solaris 8(gcc 3.2.3.0) platform using same compile options.

When I compile & run my program on 2.5.1 it is running without any problem and also it initializes all the structure variables etc properly.

But when I compile and run the same code on Solaris 8 it compiles properly but while running it is not initalizing sme of the structure elements.

Following is the scenario

main()
{
funcA(strcture A);/* This is the initializing function which sets all the structure element values.And within this function the values are getting properly populated in both the platforms*/

printf(A.c1);
......
.....
printf(A.c4);
}

when I print the values of the struture elemnts A.c1 is getting properly populated but A.c4 is not getting populated.

Can anybody help me out with this .

Following are the compiler option that I am using

gcc -g $(CF) -Wmissing-prototypes -I../include

i don't know, but there's an email help list on the gnu.gcc.org site which i found very useful when i was attempting to install gnu gcc. there's people who know the ins and outs of gcc related stuff on there. maybe give that a go.
