| nwc10 | OK, so I decided to cheat, and built the setting with a known working moarvm. and (after more cheating) I can run -e0 | 10:02 | |
| and t/01-sanity/18-simple-multisubs.t fails | |||
| (and then a bunch more) | |||
| but it's failing like this | |||
| Can't use unknown trait 'is' -> 'onlystar' in a sub declaration. | |||
| which looks very similar to the crazy in (failing) to build the setting | 10:03 | ||
| timotimo | yeah that's a multi dispatch failure reported as "you wanted something that doesn't exist" | 10:07 | |

| nwc10 | and the testcase reduces to | 10:19 | |
| multi sub foo () {} | |||

| timotimo | nice | 11:28 | |
| i just patched the visualizer to ignore heaps that have a size of 0 in their entry | 12:17 | ||
| though i must assume i'll be missing important data | |||
| firefox is having trouble opening the file ..?! | 12:19 | ||

| so what does this tell me, i wonder | |||
| Red areas are memory locations in use. | 12:27 | ||
| Gray areas are free locations, but not released back to the kernel. | |||
| White areas are freed to the kernel. | |||
| so i think that means a malloc_trim ought to release about 33.5 megabytes of memory to the kernel? | 12:28 | ||
| the visualizer writes out every little square as its own png, all of them are only a few bytes big, but use 4 kilobytes on disk because reasons | 12:29 | ||

| timotimo | tried to include github.com/theoricien/ptmalloc2v, but facing a couple of issues there as well, and the output isn't graphical, it's pages and pages and pages and pages and pages of output | 14:00 | |

| timotimo | you are supposed to call heap_init before calling malloc or calloc, but ltrd calls it already before your own binary even gets to have its entry point invoked | 14:30 | |
