the addition of -mpreferred-stack-boundary=2 to the
CFLAGS_COMMON variable
seems to be the culprit

here is the the result of 'bt' in the JIN gdb session that results from
my trying ssh valid_user AT some DOT host

#0  0x6102f300 in cygwin_getservbyname (name=0x404f52 "ssh",

FWIW
ssh seems to work fine with a DLL built with just the other new flags
CFLAGS_COMMON:=-Wall -Wwrite-strings -fno-common -pipe -Winline -fbuiltin

This is with the CVS files ~0800 EDT today

Cheers
