【问题描述】:
我正在使用gcov 在Linux 上测试我的程序(添加“-fprofile-arcs -ftest-coverage”),但是启动后程序会崩溃:
(gdb) bt
#0 0x00000034e433386f in __strlen_sse42 () from /lib64/libc.so.6
#1 0x000000000053c57a in __gcov_init ()
#2 0x000000000053c4b9 in _GLOBAL__I_65535_0_g_st_rerun_cmd_param ()
at source/rerun/aicent_ara_rerun.c:963
#3 0x000000000053dc26 in __do_global_ctors_aux ()
#4 0x0000000000403743 in _init ()
#5 0x00007fff6d6b3ce8 in ?? ()
#6 0x000000000053db55 in __libc_csu_init ()
#7 0x00000034e421ecb0 in __libc_start_main () from /lib64/libc.so.6
#8 0x0000000000404449 in _start ()
来自 __gcov_init() 源 (http://www.coreboot.org/~stepan/coreboot-coverage/lib/libgcov.c.gcov.html),
......
size_t filename_length = strlen(info->filename);
......
可以看出根本原因是“info->filename”无效(反码后地址为0x57c4ac00000000,确实无效)。
我不知道如何分析这个错误,任何人都可以提供任何线索吗?提前非常感谢!
附:我的Linux 环境:
