This will usually avail you naught, as clang is a Cygwin symlink, and 
strace as a pure Windows program doesn't understand those (which is what 
that error is trying to tell you)

$ strace $(realpath $(which clang))

shows the actual problem...

---------------------------
clang-8.exe - Entry Point Not Found
---------------------------
The procedure entry point _alloca could not be located in the dynamic 
link library C:\cygwin64\bin\cygLLVMSupport-8.dll.
---------------------------

... which does correspond to a change made in Cygwin 3.5.0.
