Which platform is this running on? That could be helpful in determining 
the cause of your problem.

On Windows XP, I wrote a GNAT GPL application that raised and handled a 
million exception occurrences. This application also does a call to the 
Win32 API function GlobalMemoryStatus both before and after handling a 
million exception occurrences. The memory status before and after 
handling these exceptions was virtually the same. This seems to indicate 
that on XP at least, GNAT exceptions do *not* leak memory.
