[lwip-devel] [bug #17922] mem_malloc bug

[Andreas Funcke]

Follow-up Comment #3, bug #17922 (project lwip):

Hello, I’m a newbie and had problems with the alignment in mem.c too. I
realized a fix which is working in the following way. I hope this information
will help others too.

mem.c (line 68)
static struct mem *ram_end;
#if 0
/* Adam original */
static u8_t ram[MEM_SIZE + sizeof(struct mem) + MEM_ALIGNMENT];
#else
// Andreas alignment fix
static __attribute__ ((aligned (MEM_ALIGNMENT))) u8_t ram[MEM_SIZE +
sizeof(struct mem) + MEM_ALIGNMENT];
/*
// Christiaan alignment fix
static u8_t *ram;
static struct mem ram_heap[1 + ( (MEM_SIZE + sizeof(struct mem) - 1) /
sizeof(struct mem))];
*/
#endif
