template ignores its type, causing codegen errors #10272
Description
reduced from a failure I had
template runTest(a: int) =
echo (a2:a) # error
# echo (a,) # error
# echo (a2:a.cint) # works
# echo a # wokrs
proc main()=
let SIGSEGV = cint(11)
# uncomment either, it'll work
runTest(SIGSEGV)
runTest(SIGSEGV + 128)
main()compiling gives:
