Subject: [PATCH 63/N] Cygwin: suppress a warning generated with w32api >=
|
|
12.0.0
|
|
|
|
w32api 12.0.0 adds the returns_twice attribute to RtlCaptureContext().
|
|
There's some data-flow interaction with using it inside a while loop
|
|
which causes a maybe-uninitialized warning.
|
|
|
|
../../../../winsup/cygwin/exceptions.cc: In member function 'int _cygtls::call_signal_handler()':
|
|
../../../../winsup/cygwin/exceptions.cc:1720:33: error: '<anonymous>' may be used uninitialized in this function [-Werror=maybe-uninitialized]
|
