Help with CC_INTERP/x86/WXP/VS2010: assert(false) failed: should never happen in frame::sender_sp()

[Francis ANDRE]

Hi

I fixed the cppInterpreter on WXP/x86/VS2010 but I got this fatal error just 
running hotspot -version
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error 
(Z:\DEV\OpenJDK_7u40\hotspot\src\cpu\x86\vm\frame_x86.inline.hpp:157), pid=1216, 
tid=3096
#  assert(false) failed: should never happen
#
# JRE version:  (7.0_40-b43) (build )
# Java VM: OpenJDK Client VM (24.0-b56-internal-debug mixed mode windows-x86 )
# Failed to write core dump. Minidumps are not enabled by default on client 
versions of Windows


from this code
inline intptr_t*    frame::sender_sp()        const {
   // Hmm this seems awfully expensive QQQ, is this really called with 
interpreted frames?
   if (is_interpreted_frame()) {
     assert(false, "should never happen");
     return get_interpreterState()->sender_sp();
   } else {
     return            addr_at(sender_sp_offset);
   }
}

but when  the assert(false, "should never happen"); is commented out, the 
hotspot runs til the end

Has someone any idea about this somewhat indoubt assert?
