This patch fixes a debugger crash when trying to print the 'first or
'last value of type Short_Integer when this type is not used in the
program (or debug info for this type is not available).
2009-03-12 Joel Brobecker <brobecker@adacore.com>
Fix segfault when printing short_integer'last.
* ada-lang.c (ada_find_any_type): Search in the primitive types
if a symbol could not be found.
A testcase is also provided.
2009-03-12 Joel Brobecker <brobecker@adacore.com>
* gdb.ada/tick_last_segv: New testcase.
Tested on amd64-linux. Checked in.
