--- Comment #30 from Martin Liška <marxin at gcc dot gnu.org> --- > CCing some folks familiar with Windows, while Martin has committed a mmap > based solution, I think it will not work on Windows, but Note the libgcov still falls back to malloc. So if there's not a custom allocator (like tcmalloc) that does not allow recursively, all should be fine.
