Summary: Enums with member initializers generate undefined
symbols
Product: DGCC aka GDC
Version: 0.24
Platform: PC
OS/Version: Linux
Status: NEW
Keywords: link-failure
Severity: critical
Priority: P2
Component: glue layer
AssignedTo: dvdfrdmn users.sf.net
ReportedBy: pseus7 gmail.com
Steps to reproduce:
----- bug.d -----
module bug;
enum GDCBUG
{
BUG = -1,
ISSUE = -2,
PROBLEM = -3
}
-----------------
Compile with:
gdmd -S bug.d
Test with:
cat bug.s | grep __s
Output:
.long ___s.898
.local ___s.898
.comm ___s.898,0,1
========================
WORKAROUND:
----- bug.d -----
module bug;
enum GDCBUG
{
GDC_WORKAROUND, //If the first member has no default value (or that value
is 0), no undefined symbols are produced.
BUG = -1,
ISSUE = -2,
PROBLEM = -3
}
-----------------
Compile with:
gdmd -S bug.d
Test with:
cat bug.s | grep __s
Output:
(empty)
========================
First experienced by the Tango guys:

Now causing lots of problems for the gtkD guys:

This still happens in gdc-0.25-4.1.2-17 from Debian Lenny.

Fixed in release 0.25 / svn 213.
Not sure if the description or the DStress cases actually test the problem(?)
Need to have two modules:
-- a.d --
enum E { A = 1, B = 2 }
-- b.d --
import a;
void main() { new E[10]; }
