Hi,<div><br></div><div>The versions of gcc that are available on FreeBSD (even on the 9.0 beta, though I haven't tested them all) will yield that error. clang compiles it fine, though. What I did was use clang to compile that file. You can also compile lldb using only clang.</div>
<div><br></div><div>If you have any more problems, please tell. But I remind you that the FreeBSD port is still very incomplete and can't be used for debugging, yet.<br><br><div>Regards,</div><div><br></div><div> Filipe</div>

<div><br></div><div>This is the first time I see a compiler being confused at this (LLDB is routinely compiled with clang and I guess several people compile it on Linux with GCC as well). This idiom is actually a quite common way to obtain one-function-specialization-inside-class-template.</div>
<div><br></div><div>In order to try and solve this, could you try to clean your LLDB build folder and try to build LLDB alone without the rest of LLVM, or using a different more recent version of GCC?</div><div><br></div>
