I'm wondering whether sizeof(uint32_t) should be replaced by kPointerSize
instead. 

+  static const int kBackup_edi = kBackup_ebx + sizeof(uint32_t);
+  static const int kBackup_esi = kBackup_edi + sizeof(uint32_t);
+  static const int kReturn_eip = kBackup_esi + sizeof(uint32_t);
+  static const int kInputBuffer = kReturn_eip + sizeof(uint32_t);
+  static const int kInputStartOffset = kInputBuffer + sizeof(uint32_t);
+  static const int kInputEndOffset = kInputStartOffset + sizeof(uint32_t);
+  static const int kRegisterOutput = kInputEndOffset + sizeof(uint32_t);
 
   // Initial size of code buffer.
   static const size_t kRegExpCodeSize = 1024;
