Summary

0000802: Compilation error for files generated by message compiler (MSGC) when field is re-assigned

Description

I was unable to compile the INET suite on Windows as I was getting the following error

MSGC: transport/rtp/RTPInterfacePacket.msg
MSGC: transport/rtp/RTPSenderControlMessage.msg
MSGC: transport/rtp/RTPSenderStatusMessage.msg

This application has requested the Runtime to terminate it in an unusual way.

omnetpp-4.6/tools/win32/mingw32/include/c++/4.9.2/bits/basic_string.h:857: std::basic_string<_CharT, _Traits, _Alloc>::reference std::basic_string<_CharT, _Traits, _Alloc>::operator[](std::basic_string<_CharT, _Traits, _Alloc>::size_type) [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; std::basic_string<_CharT, _Traits, _Alloc>::reference = char&; std::basic_string<_CharT, _Traits, _Alloc>::size_type = unsigned int]: Assertion '__pos <= size()' failed.
Makefile:944: recipe for target 'transport/rtp/RTPInterfacePacket_m.h' failed
make[1]: *** [transport/rtp/RTPInterfacePacket_m.h] Error 3

Looking more into this, I managed to reproduce with a very simple file (attached). Basically, the issue seems to occur when in a packet definition a field of the parent class (e.g., kind) is redefined like in

packet Foobar {
kind = 15;
int someField;
}

omnetpp-4.6/tools/win32/mingw32/include/c++/4.9.2/bits/basic_string.h:857: std::basic_string<_CharT, _Traits, _Alloc>::reference std::basic_string<_CharT, _Traits, _Alloc>::operator[](std::basic_string<_CharT, _Traits, _Alloc>::size_type) [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; std::basic_string<_CharT, _Traits, _Alloc>::reference = char&; std::basic_string<_CharT, _Traits, _Alloc>::size_type = unsigned int]: Assertion '__pos <= size()' failed.
Please contact the application's support team for more information.
Makefile:99: recipe for target 'Foobar_m.cc' failed
make[1]: *** [Foobar_m.cc] Error 3
If I remove "kind = 15", everything works fine. Otherwise I got the following error (similar to the INET case)

This code works fine in omnet++ 4.5 and prior version.

Can you please look into this?

Thanks a lot,

P.

I have -D_GLIBCXX_DEBUG enabled in my project but this does not create any issue. Given this, I feel the bug is less serious than I had though but still I think it would be worth investigating the root cause. Thanks P.
