The problem is in the `level' variable in the test.
(gdb) break catcher if level == INNER
A syntax error in expression, near `== INNER'.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(gdb) PASS: gdb.base/sigaltstack.exp: break catcher if level == INNER
continue
Continuing.
Program received signal SIGALRM, Alarm clock.
Program received signal SIGVTALRM, Virtual timer expired.
Program exited with code 03.
(gdb) FAIL: gdb.base/sigaltstack.exp: continue to catch (the program exited)
...
Note that the variable has the same name as the enum:
enum level { MAIN, OUTER, INNER, LEAF, NR_LEVELS };
/* Levels completed flag. */
volatile enum level level = NR_LEVELS;
It boils down to this --- before the patch, running sigaltstack
under gdb (run to main):
(gdb) p level
$1 = NR_LEVELS
(gdb) ptype level
type = volatile enum level {MAIN, OUTER, INNER, LEAF, NR_LEVELS}
and after the patch:
(gdb) p level
Attempt to use a type name as an expression
(gdb) ptype level
type = volatile enum level {MAIN, OUTER, INNER, LEAF, NR_LEVELS}

Fixed on but 7.2 branch and mainline, by reverting original patch, and adding a
new explicit test for the regression.
