Bug #: 51940
Summary: Ada.Finalization of passed function return value
skipped if exception raised in routine
Classification: Unclassified
Product: gcc
Version: 4.5.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: garynot@comcast.net
Created attachment 26409
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26409
Sample failing program. Very simple code.
When a finalizable value is returned as a function result and passed to a
routine, if that routine terminates with an exception then the Finalization
routine is not called on the function result. The value thus escapes from
finalization control when it should not.

I cannot reproduce. Can you post the output of 'gcc -v' and the gnatmake
command you use (and remove all the useless switches if possible)?

This is GNAT GPL so you need to report this to AdaCore instead.

How do I report it to AdaCore? Their web site has lots of marketing stuff but
nothing about reporting bugs. Ditto for the Libre site.
So there are two GNAT's in the world? Do they ever crosspollenate? Is the GCC
GNAT more reliable?

See the 'Contact' menu on the Libre site.

There is only one GNAT, the GNU Ada Translator, of which different versions are
released by different organizations. 'gcc -v' should be sufficient to identify
the version.
