<body><div>Hi,<br></div>
<div> </div>
<div>We're using Clang 3.3.<br></div>
<div>In a Static Analyzer checker, I'm trying to determine the size of a Type. I use ASTContext::getTypeSize on it, which works fine... usually. However, on a certain Suse Linux 11 environment, attempting to do so causes a segmentation fault inside Clang. Here is the relevant part of the stack trace:<br></div>
<div> </div>
<div>0 clang-3.3 0x000000000136b592 llvm::sys::PrintStackTrace(_IO_FILE*) + 34<br></div>
<div>1 clang-3.3 0x000000000136b219<br></div>
<div>2 libpthread.so.0 0x00007ff45b1e75d0<br></div>
<div>3 clang-3.3 0x0000000001e3bc4e clang::ASTContext::getTypeInfo(clang::Type const*) const + 62<br></div>
<div> </div>
<div>The Type passed to it dumps to 'unsigned int' identifier, and is actually a TypedefType, wrapping a BuiltinType representing unsigned int. In other environments, this causes no problem.<br></div>
<div> </div>
<div>We have no root access on this system, and the gcc 4.3 is preinstalled - we have, however, created a fakeroot with gcc 4.7.1 and other goodies. Unfortunately, we are unable to prevent Clang (and even gcc 4.7.1) from having gcc 4.3's headers in the include path. I do not know if this is relevant, though - after all, builtin types shouldn't really be affected by system headers, should they?<br></div>
<div> </div>
<div>So any idea what's going on?<br></div>
<div> </div>
<div>Thanks!<br></div>
