I'm using Glib v2.4.2. To re-create my suspicion, do the following:
1) create a file with the following (simple stuff)
/* ghelloworld.c */
#include <glib.h>
#include <mcheck.h>
int main(void) {
mtrace();
g_print("Hello World\n");
/* printf("Hello World\n"); */
muntrace();
return(0);
}
2) build it
> gcc -o ghelloworld ghelloworld.c `pkg-config --cflags glib-2.0`
`pkg-config --libs glib-2.0`
> export MALLOC_TRACE='mtrace.log'
> ./ghelloworld
(outputs a mtrace.log to the cwd)
> mtrace ghelloworld mtrace.log

3) Commenting out the g_print() and uncommenting out printf(),
rebuilding, and then running ghelloworld over again yield no memory
leaks (according to mtrace).
Am I using g_print incorrectly? More specifically, am I misusing or not
initializing something?
