class RelocationDirectory : pepp::msc::NonCopyable
{
private:
//! Setup the directory
void _setup(Image* image) {
m_image = image;
m_base = reinterpret_cast<decltype(m_base)>(
&image->base()[image->getPEHdr().rvaToOffset(
image->getPEHdr().getOptionalHdr().getDataDir(DIRECTORY_ENTRY_BASERELOC).VirtualAddress)]); //this line
m_section =
&image->getSectionHdrFromVa(image->getPEHdr().getOptionalHdr().getDataDir(DIRECTORY_ENTRY_BASERELOC).VirtualAddress);
}
}
In the line of m_base = *, rvaToOffset may return zero like empty relocation table.
