[英]GDB shows no backtrace from application with debug symbols
我用-g
和-O0
編譯了我的可執行文件,當我用gdb運行它並得到std::bad_function_call
由於某些原因,gdb在我的應用程序中不顯示任何有關其起源的信息。 順便說一句,應用程序有兩個線程,最可能的異常不是來自主線程。
回溯這么差的原因可能是什么?

您的/usr/lib/x86_64-linux-gnu/libstdc++.so.6
副本可能被不正確地剝離或以其他方式損壞。
這是一個測試程序:
#include <functional>
std::function<int()> foo;
void *thr(void *)
{
foo();
}
int main()
{
pthread_t tid;
pthread_create(&tid, nullptr, thr, nullptr);
pthread_join(tid, nullptr);
}
使用以下命令進行構建: g++ -g -std=c++11 t.cc
,然后:
gdb -q ./a.out
Reading symbols from ./a.out...done.
(gdb) run
Starting program: /tmp/a.out

如果沒有得到相同的結果(我想不會),請嘗試從libstdc++6
軟件包重新安裝libstdc++.so.6
。 安裝libstdc++6-dbg
也可能有所幫助。
