Missing DWARF debug information #15360
Description
Bug Report
https://github.com/SimonKagstrom/kcov uses DWARF debug information to power its code coverage reporting. While viewing the reports more closely I notice that it reports certain things as missed even tho they were most definitely hits. For example with the following code:
# test.cr
class Foo
getter callback : Proc(Int32, Int32)? = nil
def callback(&@callback : Int32 -> Int32) : Nil
end
end
foo = Foo.new
foo.callback do |val|
val * 10
end
pp foo.callback.not_nil!.call 10Generate the report:
$ crystal build --debug test.cr
$ kcov --include-path=./test.cr ./coverage ./test
100
$ xdg-open coverage/index.htmlResults in:
The block body and the calling of the proc are reported as missed, even tho you can clearly see 100 in the console output. Using getter! instead of an explicit not_nil! makes it correctly report that line as a hit.
I think this implies those specific lines are missing debug information?
