hello,every one:
我的系统环境是：
system：centos 6.3 x86_64
kernel：Linux localhost 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

问题：
当我执行
./sample-bt -p 2080 -u -t 5 >a.bt
报错，在pass 4的时候报错，报错内容如下：
gcc: 内部错误：已杀死 (程序 cc1)
请提交一份完整的错误报告。
具体步骤请参见 <http://bugzilla.redhat.com/bugzilla>。
make[1]: *** [/tmp/stapuZrcYR/stap_0df1b43dbb169a80ee2a151bbcd6e476_6388_src.o] 错误 1
make: *** [_module_/tmp/stapuZrcYR] 错误 2
WARNING: kbuild exited with status: 2
Pass 4: compilation failed. [man error::pass4]
我将其stap源码dump下来，直接用stap执行，报错信息如下：
./sample-bt -p 2080 -u -t 5 -d >a.stp：
probe begin {
warn(sprintf("Tracing %d (/usr/local/nginx/sbin/nginx) in user-space only...\n", target()))
}
global bts;
global quit = 0;
probe timer.profile {
if (pid() == target()) {
if (!quit) {
bts[ubacktrace()] <<< 1;
} else {
foreach (bt in bts- limit 1024) {
print_ustack(bt);
printf("\t%d\n", @count(bts[bt]));
}
exit()
}
}
}
probe timer.s(5) {
nstacks = 0
foreach (bt in bts limit 1) {
nstacks++
}
if (nstacks == 0) {
warn("No backtraces found. Quitting now...\n")
exit()
} else {
warn("Time's up. Quitting now...(it may take a while)\n")
quit = 1
}
}
执行代码报错：
