           Summary: std.loader is broken on linux
           Product: D
           Version: 0.168
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: link-failure, patch
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: h3r3tic at mat.uni.torun.pl

There are three problems with std.loader:

1. It's not compiled into libphobos.a
2. When compiled-in, gcc complains about a duplicate RTLD_NOW symbol, the
second instance exists in std.c.linux.linux.
3. When the conflicting symbols are resolved (e.g. by replacing the RTLD_NOW
usage in std.loader to its numeric value, 0x00002), lib loading doesn't work in
linux because of the line 339 in loader.d:

ExeModuleInfo   mi = s_modules[moduleName];

it should be changed to:

ExeModuleInfo*   mi_p = moduleName in s_modules;
ExeModuleInfo   mi = mi_p is null ? null : *mi_p;
