 Using a log file from an ARM based system led to the following error:

 Typelib segfaults when loading a tlb file with /std/string defined as
 /uint8_t. The following test cases towards narrowing down the error.

 case one: segfaulting
 {{{
 <?xml version="1.0"?>
 <typelib>
   <numeric name="/uint8_t" category="uint" size="1" />
   <container name="/std/string" of="/uint8_t" size="4"
 kind="/std/string"/>
 </typelib>
 }}}
 case two: Exception
 {{{
 <?xml version="1.0"?>
 <typelib>
     <numeric name="/uint8_t" category="uint" size="1" />
    <numeric name="/int8_t" category="sint" size="1" />
   <container name="/std/string" of="/uint8_t" size="4"
 kind="/std/string"/>
 </typelib>
 }}}
 {{{
 test.rb:7:in `merge_xml': cannot load xml: std::string can only be built
 on top of '/int8_t' -- found /uint8_t (ArgumentError)
         from test.rb:7:in `<main>'
 }}}

 case 3: no error
 {{{
 <?xml version="1.0"?>
 <typelib>
     <numeric name="/int8_t" category="sint" size="1" />
   <container name="/std/string" of="/sint8_t" size="4"
 kind="/std/string"/>
 </typelib>
 }}}
