reduced test case
Hi,
the attached small.cc creates an ICE when compiled with -fsanitize=undefined
initially the ICE was triggered by a single error in > 100.000 lines C++ code.
gcc -c -fsanitize=undefined small.cc
small.cc:2:3: error: expected '{' before 'inline'
inline namespace __cxx11 __attribute__((__abi_tag__ ("cxx11"))) { }
^~~~~~
[...]
small.cc:151:1: error: expected '}' at end of input
small.cc:126:12: warning: inline function 'T*
std::TB5Util::SOCmnPointer<T>::p() const [with T =
std::TB5Util::OTClientSession]' used but never defined
inline T* p() const;
^
small.cc:134:24: warning: inline function 'const tstring&
std::TB5Util::OTClientSession::getUrl() const' used but never defined
inline const tstring& getUrl() const;
^~~~~~
small.cc: In member function 'std::TB5Util::EnumStatusCode
std::TB5Util::SecureChannel::removeSession(std::TB5Util::OTClientSessionPtr,
bool)':
small.cc:150:121: internal compiler error: tree check: expected class 'type',

session->getUrl();
