请教 mips 运行 Valgrind 段错误 signal 11 (SIGSEGV) P

alex0a

我想在MIPS下用Valgrind ，但是总是死机，自己编了个小程序，还是死机，Process terminating with default action of signal 11
运行环境：MIPS linux 32 嵌入式单板 ，运行程序非常简单，代码如下
main (){
while(1){
sleep(1);
printf("tst    ================\n");
}}
。
运行Valgrind 报错如下=================================================

命令： ./mips-linux-gnu-valgrind --tool=memcheck ./a.out

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.



In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.
