--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
Reduced testcase.  Appears to be blowing up in the dwarf2 bits.

Compile with -Os -mint32 -mh -fomit-frame-pointer -g

typedef _Bool bool;
typedef unsigned short umode_t;
enum {
 false = 0,
 true = 1
};
struct dentry {
 struct inode *d_inode;
};
struct path {
 struct dentry *dentry;
};
extern int vfs_create(struct inode *, struct dentry *, umode_t, bool);


long SYSC_mknodat(int dfd, const char * filename, umode_t mode, unsigned dev)
{
 struct dentry *dentry;
 struct path path;
 int error;
 unsigned int lookup_flags = 0;
 switch (mode & 00170000) {
  case 0: case 0100000:
   error = vfs_create(path.dentry->d_inode,dentry,mode,true);
   break;
  case 0020000: case 0060000:
   error = vfs_mknod(path.dentry->d_inode,dentry,mode, new_decode_dev(dev));
   break;
 }
}
