Since we introduced the API to set signal handler and print a stacktrace, we should avoid glibc's backtrace, which may call malloc. Basically, we choose the way to produce a stacktrace as same as perftools. Also, I removed GetStackFrames, which is not used and not implemented with glibc. git-svn-id: https://google-glog.googlecode.com/svn/trunk@16 eb4d4688-79bd-11dd-afb4-1d65580434c0

// This is similar to the GetStackFrames routine, except that it returns

// the stack trace only, and not the stack frame sizes as well.

|
|
// main() { foo(); }
|
|
// foo() { bar(); }
|
|
// bar() {
|
|
// void* result[10];
|
|

// result[1] main

// "result" must not be NULL.
