Hi, I think there's a bug in gc_realloc, after calling it a few times it returns NULL even though there's enough memory to satisfy the request.. This is the code I'm using to test:
void test_realloc()
{
printf("testing realloc\n");
void *mem = gc_alloc(100);
for (int i=1; i<=50; i++) { /* ~50K */
mem = gc_realloc(mem, 1000*i);
printf("realloc: %d\n", 1000*i);
if (mem==NULL) {
pyb_info();
printf("\r\n");
sys_tick_delay_ms(5000);
__asm__ volatile ("BKPT");
}
}
}
I call test_realloc() after running the main script in main.c
This is the result:
realloc: 37000 <<< stops here
