It might very well be. I also noticed the output of ldd is not reproducible.
It shows different duplicate entries when run repeatedly and the load
address you marked is also a duplicate:

cyggcc_s-seh-1.dll => /usr/bin/cyggcc_s-seh-1.dll (0x3fdf60000)

Hm, is gdb dependent on gcc? I just noticed my gcc is apparently broken:
pc> cygcheck -c gcc

P.S.:
pc> cygcheck -c gcc
Cygwin Package Information
Package Version Status
pc> gcc -v
Using built-in specs.
