+Subject: modules/speller/default/vector_hash-t.hpp: fix gcc-15 build
+
+Uncoming `gcc-15` added extra checks for template instantiation that is
+guaranteed to fail in
+  https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=313afcfdabeab3e6705ac0bd1273627075be0023
+
+As a result `aspell` build now fails as:
+
+    In file included from modules/speller/default/readonly_ws.cpp:51:
+    modules/speller/default/vector_hash-t.hpp: In member function 'void aspeller::VectorHashTable<Parms>::recalc_size()':
+    modules/speller/default/vector_hash-t.hpp:186:43: error: 'class aspeller::VectorHashTable<Parms>' has no member named 'e'
+      186 |     for (iterator i = begin(); i != this->e; ++i, ++this->_size);
+          |                                           ^
+    modules/speller/default/vector_hash-t.hpp:186:59: error: 'class aspeller::VectorHashTable<Parms>' has no member named '_size'; did you mean 'size'?
+      186 |     for (iterator i = begin(); i != this->e; ++i, ++this->_size);
+          |                                                           ^~~~~

+
+It looks like `_size` is `size_` mis-spelling and `e` was not introduced
+here.
