I'm using 8.0.0.
When in include "exceptions.h", I want to get for "Exc" a list of completions
like '("ExcCompatibility" "ExcDimensionMismatch"
"ExcDimensionMismatch2" "ExcDisabled" "ExcDivideByZero"
"ExcEmptyObject" "ExcFileNotOpen" "ExcGhostsPresent" "ExcIO"
"ExcImpossibleInDim" "ExcIndexRange" "ExcInternalError"
"ExcInvalidConstructorCall" "ExcInvalidIterator" "ExcInvalidState"
"ExcIteratorPastEnd" "ExcLowerRange" "ExcMemoryLeak" "ExcMessage"
"ExcNeedsLAPACK" "ExcNeedsMETIS" "ExcNeedsNetCDF" "ExcNeedsPETSC"
"ExcNeedsUMFPACK" "ExcNotImplemented" "ExcNotInitialized"
"ExcNotMultiple" "ExcNumberNotFinite" "ExcOutOfMemory"
"ExcPureFunctionCalled" "ExcScalarAssignmentOnlyForZeroValue"
"ExcZero" "ExceptionBase" "exc_name" "ExcDivideByZero"
"ExcNumberNotFinite" "ExcOutOfMemory" "ExcMemoryLeak" "ExcIO"
"ExcFileNotOpen" "ExcNotImplemented" "ExcInternalError"
"ExcPureFunctionCalled" "ExcInvalidConstructorCall"
"ExcNotInitialized" "ExcInvalidState" "ExcImpossibleInDim" "ExcZero"
"ExcEmptyObject" "ExcDimensionMismatch" "ExcDimensionMismatch2"
"ExcIndexRange" "ExcLowerRange" "ExcNotMultiple" "ExcInvalidIterator"
"ExcIteratorPastEnd" "ExcMessage" "ExcCompatibility"
"ExcScalarAssignmentOnlyForZeroValue" "ExcNeedsLAPACK"
"ExcNeedsUMFPACK" "ExcNeedsMETIS" "ExcNeedsPETSC" "ExcNeedsNetCDF"
"ExcGhostsPresent" "ExcDisabled" "exchange_data" "exc" "Exceptions"
"exceptions" "ExceptionBase" "exclusive" "exception_ptr"
"exception_ptr_static_exception_object"
"exception_ptr_static_exception_object::e" "exception_detail"
"exception" "exception_wrapper").

I'm getting an error instead. The default
`semantic-analyze-possible-completions' produces only one result out
of the whole
list, while all of them are acceptable from C++ point of view.

Doesn't work for `semantic-collector-calculate-completions':
eieio--defmethod: Unknown class type semantic-collector-abstract in
method parameters

I attach the debug output. It's quite big.
Also I've made some bisections: 8601 works, but 8607 doesn't.
I'll keep going with that.
