Below are two _consecutive!_ runs of ldd on th= e very same executable. Why the output differs so drastically (including t= he unknown dlls all of a sudden)? Another round of consecutive calls of ldd on the very same executable file,= and a similar "indeterministic" result (the executable itself is much simp= ler than the one from my previous post, so the list of DLLs is quite short): 1. ntdll.dll =3D> /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffc339d00= 00) KERNEL32.DLL =3D> /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffc= 31a00000) KERNELBASE.dll =3D> /cygdrive/c/WINDOWS/System32/KERNELBASE.dll (0x= 7ffc30090000) cyggcc_s-seh-1.dll =3D> /usr/bin/cyggcc_s-seh-1.dll (0x3ee3a0000) ??? =3D> ???
