commit a93a85a1ff3ca937dabb1d985381b27836ce1bfc Author: Ken Brown <[email protected]> Date: Thu Aug 20 09:47:47 2020 -0400 Cygwin: strace: ignore GCC exceptions Any C++ app that calls 'throw' on 64-bit Cygwin results in an exception of type STATUS_GCC_THROW (0x20474343) generated by the C++ runtime. Don't pollute the strace output by printing information about this and other GCC exceptions.
