digitalmars.D.bugs - [Issue 19718] New: DMD 2.085 changes to gsroa make DCD crashing


          Issue ID: 19718
           Summary: DMD 2.085 changes to gsroa make DCD crashing
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: b2.temp gmx.com

shell script to reproduce the issue and verify that it's fixed:

killall dcd-server

if [[ ! -d dcd ]]; then
    git clone https://github.com/dlang-community/dcd.git
    git submodule update --init

cd dcd

if [[ ! -f bin/dcd-server ]]; then

pos=`grep -boa "ASTVisitor" libdparse/src/dparse/ast.d | head -1`
pos=`echo $pos | grep -o [0-9]*`
let pos++

bin/dcd-server &
sleep 2
res=`bin/dcd-client --doc -c$pos libdparse/src/dparse/ast.d`

if [[ ${res} == "Implements the \$(LINK2
http://en.wikipedia.org/wiki/Visitor_pattern, Visitor Pattern)\nfor the various
AST classes" ]]; then
    echo "FIXED !!"

Note that you'll certainly have to tweak the makefile of DCD in order to use
the devel version of DMD, line 9 (DMD := <your devel dmd here...>)
Manual digging in the stable branch shows that the regression come from this
