Thanks for reporting this problem, and the test case.

This is related to the thread name support added in 2.6.0
The exception used to pass the thread name to the debugger is supposed
to be caught internally if the debugger doesn't handle it, but this
doesn't seem to be working correctly on x86.

At the moment, the workaround would be to downgrade to Cygwin 2.5.2, or
to update to the gdb 7.11.1-1 test release (which has explicit handling
for these thread naming exceptions)
