Problem was originally found in a MinGW port of gcc 4.2.1, but production of a
reduced test case removed all Windows-specific code.

The problem does not occur with the gcc 4.1.2 compiler distributed with Fedora.

Bug #29015 may be related. It is produced when using Ada 2005 new features.
This bug is found in code that uses no Ada 2005 features.
