Prevent the compiler from failing with an internal error in some cases involving
an instance of a generic which takes as a formal parameter an instance of a
second generic, where the second generic has an Initial_Condition aspect
specification.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* contracts.adb
(Analyze_Package_Contract): Do not analyze the contract of a
temporary package created just to check conformance of an actual
package.
