Memory leak in nleqslv()
...2.4 GB
While running it with 10 iterations uses far less memory, only 95MB:
Running it once has my rsession with 62Mb of use, so growth in memory
allocation scales with iterations.
Even after 1000 iterations, with 2+ GB of memory used by the R
session, no large-sized objects are listed, although mem_use() shows
2+ GB of memory used.
test_iter lambda res_ext reserves x_test
48 1648 1648 1648 3256
I've replicated this on OS-X and in Windows both on a desktop and a
Surface Pro, however colleagues have run this on their machines and
not found the same result....
