--- Comment #21 from Óscar Fuentes <gcc_bugzilla at axeitado dot com> --- (In reply to Eric Botcazou from comment #20) > Weird, I don't have any dependency on the DLL for it: > > $ ldd t.exe > ntdll.dll => /Windows/SYSTEM32/ntdll.dll (0x7ffc65560000) > ntdll.dll => /Windows/SysWOW64/ntdll.dll (0x770b0000) > wow64.dll => /Windows/System32/wow64.dll (0x5d1b0000) > wow64win.dll => /Windows/System32/wow64win.dll (0x5d210000) > > Can you post the output of 'g++ foo.cpp -v' for your C++ testcase? Can you > find out what symbol(s) of libstdc++.dll are referenced by your executable? ldd does not list libstdc++.dll, but `Dependency Walker` lists both libstdc++.dll and libgcc_s_dw2-1.dll.
