[dmd-beta] dmd 2.053 beta (Stack Overflow)

[Nick Sabalausky]

I'm getting a stack overflow with the 2.053 beta (Windows). This one's 
probably going to be a PITA to narrow down, if even possible, but here's 
what I know so far before trying to narrow anything:

On the current trunk on SemiTwist D Tool (revision 220):
http://www.dsource.org/projects/semitwist/browser/trunk
svn co -r 220 http://svn.dsource.org/projects/semitwist/trunk 
SemiTwistDTools

Building the unittest app will cause DMD to get a Stack Overflow in this new 
beta (works fine in 2.052). The cmd line sent to DMD is this:

dmd -debug -g -unittest -wi -debug=SemiTwistDLib_unittest -Isrc -of"bin\semitwist-unittests-debug.exe" 
 -I"src\semitwist\apps\tests\unittests" 
"src\semitwist\apps\tests\unittests\main.d" "src\semitwist\util\text.d" 
"src\semitwist\cmdlineparser.d" "src\semitwist\util\unittests.d" 
"src\semitwist\treeout.d" "src\semitwist\cmd\all.d" 
"src\semitwist\util\io.d" "src\semitwist\cmd\plain.d" 
"src\semitwist\util\os.d" "src\semitwist\util\ver.d" 
"src\semitwist\util\all.d" "D:\DevTool\dmd\bin\..\src\phobos\crc32.d" 
"src\semitwist\util\mixins.d" "src\semitwist\util\array.d" 
"src\semitwist\util\functional.d" "src\semitwist\util\ctfe.d" 
"src\semitwist\util\process.d" "src\semitwist\refbox.d" 
"src\semitwist\util\container.d" "src\semitwist\util\reflect.d"

If I add the -v switch, here's the verbose output:

Stack overflow

Don't know if that helps. Probably not. I'll see if I can narrow it down, 
but being a stack overflow, I don't know: Maybe it's infinite recursion 
somewhere, or maybe the stack just isn't big enough.
