My uname is similar:
CYGWIN_NT-6.1-WOW 1.7.35(0.287/5/3) i686

I don't see anything odd about gdb or anything else in cygcheck -srv 
(attached and some items obfuscated with "xxx").
I did get a warning about setup being old and it did upgrade a lot of 
packages when I was installing gdb yesterday. I saw some errors go by 
near the end of the upgrade but then downloaded the latest setup and 
re-installed gdb and saw no more errors/warning with new setup but gdb 
still crashed. Tried installing cgdb too but it also crashes since it 
apparently uses gdb. Don't see problems with other cygwin packages I use 
all the time like git and gcc.
