Subject: [dpdk-users] segmentation fault after using rte_malloc()
Date: Fri, 19 Apr 2019 09:11:05 +0800
Message-ID: <5BDADE86-3D04-4BE5-AC95-03BE123ED42B@csie.io> (raw)

	Hi all, 

	i have 1 problem while using rte_malloc

	Every time I use this function and use the memory it returns, it shows segmentation fault(core dump)

	Is something wrong?

	thanks.


	rte init …
	………...
	unsigned char *str1;
	printf("str1 addr = %x\n", str1);
	str1 = rte_malloc(NULL,2,RTE_CACHE_LINE_SIZE);
	printf("str1 addr = %x\n", str1);
	str1[0] = 'a’; //segmentation fault here
	str1[1] = '\0';
