Hi Peter,
this looks like an issue solved by this patch on MICO HEAD, isn't it?
Sun Jan 3 18:59:34 CET 2010 Karel Gardas <kgar...@objectsecurity.com>
* fix "miscompilation" of typecode.cc by GNU C++ >= 4.4
This patch fixes typecode.cc to not use TK_RECURSIVE definition since
this makes GNU C++ >= 4.4 miscompiling several of typecode.cc's switch
statements where it simply omits case blocks where TK_RECURSIVE is
used, since TK_RECURSIVE provides value which is not defined in the
TCKind enum type. Whole behaviour is completed by emitted warnings:
typecode.cc:<line>: warning: case label value is less than minimum
value for type
Unfortunatelly GCC community members claim the compiler is right here
so I enhanced tckind.h by a provided bootstrap patch to include
tk_recursive value inside the TCKind enum definition which makes GNU
C++ happy and resulting MICO working again. For more information about
this issue see GCC PR#42576
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42576)
Thanks!
Karel
