本文介绍了c ++堆栈跟踪从未处理的异常？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 这个问题之前已经问过，并且有windows特定的答案，但没有令人满意的gcc答案。我可以使用 set_terminate（）设置一个将被调用的函数（代替 terminate（）未处理的异常被抛出。我知道如何使用backtrace库从程序中的给定点生成堆栈跟踪。然而，这将不会帮助当我终止替换被调用，因为在那一点堆栈已解开。This question has been asked before and there have been windows-specific answers but no satisfactory gcc answer. I can use set_terminate() to set a function that will be called (in place of terminate()) when an unhandled exception is thrown. I know how to use the backtrace library to generate a stack trace from a given point in the program. However, this won't help when my terminate-replacement is called since at that point the stack has been unwound.然而，如果我只允许程序 abort（），它会产生一个core-dump从抛出异常的点的完整堆栈信息。所以信息是有的 - 但是有一个编程的方式来获取它，例如所以它可以记录，而不必检查一个核心文件？Yet if I simply allow the program to abort(), it will produce a core-dump which contains the full stack information from the point at which the exception was thrown. So the information is there -- but is there a programmatic way to get it, for example so it can be logged, rather than having to examine a core file?推荐答案已编辑答案：您可以使用 std :: set_terminate#include <cstdlib>#include <iostream>#include <stdexcept>#include <execinfo.h>voidhandler(){ void *trace_elems[20]; int trace_elem_count(backtrace( trace_elems, 20 )); char **stack_syms(backtrace_symbols( trace_elems, trace_elem_count )); for ( int i = 0 ; i < trace_elem_count ; ++i ) { std::cout << stack_syms[i] << "\n"; } free( stack_syms ); exit(1);}int foo(){ throw std::runtime_error( "hello" );}void bar(){ foo();}void baz(){ bar();}intmain(){ std::set_terminate( handler ); baz();}提供此输出：samm@macmini ~> ./a.out./a.out [0x10000d20]/usr/lib/libstdc++.so.6 [0xf9bb8c8]/usr/lib/libstdc++.so.6 [0xf9bb90c]/usr/lib/libstdc++.so.6 [0xf9bbaa0]./a.out [0x10000c18]./a.out [0x10000c70]./a.out [0x10000ca0]./a.out [0x10000cdc]/lib/libc.so.6 [0xfe4dd80]/lib/libc.so.6 [0xfe4dfc0]samjmill@bgqfen4 ~>assuming you have debug symbols in your binary, you can then use addr2line to construct a prettier stack trace postmortemsamm@macmini ~> addr2line 0x10000c18/home/samm/foo.cc:23samm@macmini ~>原始答案在以下我以前使用 boost :: error_info 使用 backtrace 从 execinfo.h 将堆栈跟踪注入到异常抛出。I've done this in the past using boost::error_info to inject the stack trace using backtrace from execinfo.h into an exception that is thrown.typedef boost::error_info<struct tag_stack_str,std::string> stack_info;然后当捕获异常时，可以执行Then when catching the exceptions, you can do} catch ( const std::exception& e ) { if ( std::string const *stack boost::get_error_info<stack_error_info>(e) ) { std::cout << stack << std::endl; }} 这篇关于c ++堆栈跟踪从未处理的异常？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
