Cauterite <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from Cauterite <[email protected]> --- I highly suspect this issue has already been resolved. Here's a simple test: import core.memory; void main() { // allocate and free lots of 10MB arrays foreach (_; 0 .. 1000) { auto x = GC.calloc(10_000_000, 1); GC.free(x); x = null; }; import std.c.stdio; printf("done\n"); getchar(); }; if you remove the `GC.free(x)` the working set will grow to >1GB. if you leave it in, memory usage is normal ~15MB or so. so the GC is definitely releasing pages back to the OS when it deallocates. And before you ask, yes I am linking with SNN.lib --
