Hello,
I've just switched from kernel 2.6.11_1.27_FC3 to 2.6.11_1.35_FC3.
The following program makes a segmentation violation when I use the new
kernel. When I switch back to the previous one, the program runs
without problems.
The problem occurs when the callback function is called (in
process_datas function). Calling such a nested function should be ok,
when I read the gcc documentation.
Did I miss something ?
Thanks for your help.
#include <stdio.h>
struct context_t {
int (*write_callback) ( FILE * output, char * buffer );
};
int process_datas ( struct context_t * context ) {
return ( context->write_callback ( stdout, "write call back
datas" ));
}
int test ( void ) {
struct context_t context;
int write_callback ( FILE * output, char * buffer ) {
return (fprintf ( output, "%s\n", buffer ));
}
context.write_callback = write_callback;
return (process_datas ( &context ));
}
int main ( int argc, char ** argv ) {
printf ("test result = %d\n", test());
return (0);
}
