Message-ID: <BN6PR09MB2227BA2644949DB75A67A6B2A5F60@BN6PR09MB2227.namprd09.prod.outlook.com> (raw)
Well, I don't think there's anything special that Cygwin does to load executables, because these are essentially Windows processes, so they are loaded by Windows, first and foremost.
But it gets even weirder. Below are two _consecutive!_ runs of ldd on the very same executable. Why the output differs so drastically (including the unknown dlls all of a sudden)?
1.
ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffc339d0000)
KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffc31a00000)

cygpcre-1.dll => /usr/bin/cygpcre-1.dll (0x3eb1a0000)
cyggcc_s-seh-1.dll => /usr/bin/cyggcc_s-seh-1.dll (0x3ee3a0000)
cygstdc++-6.dll => /usr/bin/cygstdc++-6.dll (0x3ea280000)
