Vk.heap_bytes pulled the Vk module - and on lang/uifree the GL window path - into a plain program, which then failed to link (_cgl_offscreen, lgl_GetError). Os.heap_bytes is malloc_zone_statistics through a weak reference (0 where there is none, and on Windows). Reseeded. Docs for it and for Json.free / Json.free_all.

bump: patch
type: fix
A string made in the middle of an expression is freed once it has been used. a + "/" + b made
a + "/", copied it and kept it for ever; a template made one such piece per hole, plus each
number's text; and a side of == built only to be compared stayed too. The compiler now frees each
of those as soon as the next +, the comparison or print has read it, and string(n) hands back
the start of what it allocated so its text can be freed at all. A string held anywhere - a
variable, an argument, a function's result - is left alone. A loop of 20,000 template builds grew
2.9 MB and now grows 0 (examples/lang/string_temps.ludic).
A slice of a string (s[a .. b], always a copy) counts too: path[0 .. n - 4] + ".dds" and
path[n - 4 .. n] == ".png" no longer leave the slice behind.
Os.heap_bytes() reads malloc's live bytes (macOS; 0 elsewhere) with no renderer linked in, for a
test that a path allocates nothing.
