> 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)?

Another round of consecutive calls of ldd on the very same executable file, and a similar "indeterministic" result (the executable itself is much simpler than the one from my previous post, so the list of DLLs is quite short):

1.
        ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffc339d0000)
        KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffc31a00000)
        KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll (0x7ffc30090000)
        cyggcc_s-seh-1.dll => /usr/bin/cyggcc_s-seh-1.dll (0x3ee3a0000)
        ??? => ??? (0xc90000)
        cygwin1.dll => /cygdrive/u/2.4.0/release/Cygwin-64/bin/cygwin1.dll (0x180040000)

2.
        ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffc339d0000)
        KERNEL32.DLL => /cygdrive/c/WINDOWS/System32/KERNEL32.DLL (0x7ffc31a00000)
        KERNELBASE.dll => /cygdrive/c/WINDOWS/System32/KERNELBASE.dll (0x7ffc30090000)
        cygwin1.dll => /cygdrive/u/2.4.0/release/Cygwin-64/bin/cygwin1.dll (0x180040000)
        cyggcc_s-seh-1.dll => /usr/bin/cyggcc_s-seh-1.dll (0x3ee3a0000)

How can that be?
