Subject: [PATCH] Make pascal_language::print_type handle varstring==nullptr
PR gdb/31524 points out a crash when pascal_language::print_type is
called with varstring==nullptr. This crash is a regression arising
from the printf/pager rewrite -- that indirectly removed a NULL check
from gdb's "puts".
This patch instead fixes the problem by adding a check to print_type.
Passing nullptr here seems to be expected in other places (e.g., there
is a call to type_print like this in expprint.c), and other
implementations of this method (or related helpers) explicitly check
for NULL.
I didn't write a test case for this because it seemed like overkill
for a Pascal bug that only occurs with -i=mi. However, if you want
one, let me know and I will do it.
