[Octave-bug-tracker] [bug #55492] "make check" crashes with jit (llvm 4.0.1)

[Julien Bect]

Follow-up Comment #3, bug #55492 (project octave):

I think that I have found the explanation in LLVM's 4.0.1
RTDyldMemoryManager.h:


  /// Legacy symbol lookup - DEPRECATED! Please override findSymbol instead.
  ///
  /// This method returns the address of the specified function or variable.
  /// It is used to resolve symbols during module linking.
  virtual uint64_t getSymbolAddress(const std::string &Name) {
    return getSymbolAddressInProcess(Name);
  }

  /// This method returns a RuntimeDyld::SymbolInfo for the specified
function
  /// or variable. It is used to resolve symbols during module linking.
  ///
  /// By default this falls back on the legacy lookup method:
  /// 'getSymbolAddress'. The address returned by getSymbolAddress is treated
as
  /// a strong, exported symbol, consistent with historical treatment by
  /// RuntimeDyld.
  ///
  /// Clients writing custom RTDyldMemoryManagers are encouraged to override
  /// this method and return a SymbolInfo with the flags set correctly. This
is
  /// necessary for RuntimeDyld to correctly handle weak and non-exported
symbols.
  JITSymbol findSymbol(const std::string &Name) override {
    return JITSymbol(getSymbolAddress(Name), JITSymbolFlags::Exported);
  }
