Thread system error value not preserved when tracing #5
Description
When tracing an executable, the tracing code interferes with the thread's system error code, which can cause incorrect execution of the traced process.
Example:
#include <iostream>
#include <Windows.h>
int main()
{
SetLastError(1337);
std::cout << "Last error: " << GetLastError() << std::endl;
std::cout << "Last error: " << GetLastError() << std::endl;
}Output (without tracing):
Last error: 1337
Last error: 1337
Output (with tracing):
...
