More significantly, abidw and its dependencies are compiled within a
standardised Android build environment (Clang, compile flags, libc++ etc.).
With the attached file, libc.so, about 4% of
abidw libc.so --out-file /dev/null
invocations result in an infinite loop.
The line
<class-decl name='DIR' is-struct='yes' visibility='default'
is-declaration-only='yes' id='type-id-1114'/>
is emitted in a tight loop.
