[Bug libstdc++/39569] Apparent memory corruption in std::stringstream after calling syslog()

Your code triggers undefined behaviour here:

const char* OutBuf = reinterpret_cast<const char*>(OutStream.str().c_str());

because str() returns a temporary string, which then dies, leaving OutBuf
pointing to unallocated memory. Just copy that temporary somewhere, dunno:

std::string outstr = OutStream.str(); 
const char* OutBuf = outstr.c_str();

or something similar.
