Cannot use user-defined types in typedef of template function
-------------------------------------------------------------
Key: TS-125
URL: https://issues.apache.org/jira/browse/TS-125
Project: Traffic Server
Issue Type: Bug
Components: Portability
Environment: OpenSolaris with SunStudio (gcc on opensolaris fails the
same code with a different error; same workaround fixes it)
Reporter: Nick Kew
Priority: Critical
This appears to be related to Sun bug
http://bugs.sun.com/view_bug.do?bug_id=6906118
but is sufficiently different that the workaround suggested there doesn't apply.
Compiling DAllocator.h produces the following fatal error:
"DAllocator.h", line 86: Error: Unexpected type name "AllocPoolDescriptor"
encountered.
"DAllocator.h", line 87: Error: Unexpected type name "AllocDescriptor"
encountered.
It can be worked around by reverting:

int alignment;
int el_size;
- SList(AllocPoolDescriptor,link) pools;
- Que(AllocDescriptor,link) free_list;
+ SLL<AllocPoolDescriptor> pools;
+ Queue<AllocDescriptor> free_list;
Expanding that with the -E option to CC reveals that this loses an offsetof
argument, so if we could fix the offset to zero then the problem goes away. If
at all possible, it would be good to make "link" the first element of
AllocDescriptor and AllocPoolDescriptor so the need for offsetof goes away.
