@fzakaria:one.ems.hostfzakariawould be nice to document how to get past that.22:40:48
@xokdvium:matrix.orgSergei Zimmerman (xokdvium) NIX_HARDENING_ENABLE=$(printLines $NIX_HARDENING_ENABLE | grep -v fortify) (ref eelco) 22:42:38
@fzakaria:one.ems.hostfzakariaokay let me try that because debugoptimized22:43:59
@fzakaria:one.ems.hostfzakariastill skips stuff22:44:01
@xokdvium:matrix.orgSergei Zimmerman (xokdvium) ma27: thanks for the gdb fix btw. Very much appreciated to be able to use boost's pretty-printers out of the box. I hate how many hoops one has to jump through to get rid of -Wa,--compress-debug-sections though 23:21:53

@lovesegfault:matrix.orglovesegfaultcould one reasonably write a nix evaluator without a GC and use refcounting, or would there be too many leaks due to cycles?04:07:54
@k900:0upti.meK900Definitely too many cycles without any form of GC04:16:48
@k900:0upti.meK900But you can probably get something out of refcounting compared to baseline04:17:27
@lovesegfault:matrix.orglovesegfaultthat's a shame, i was thinking that conceptually it'd be nice to write an evaluator around rust futures 04:17:31
@lovesegfault:matrix.orglovesegfaultbut no gc there04:17:55
@k900:0upti.meK900 That would be insanely inefficient tbh 04:18:57
@k900:0upti.meK900 Well, I guess it depends on how big your future state machine gets 04:19:24
@k900:0upti.meK900 But I'd expect it to get pretty big 04:19:30
@lovesegfault:matrix.orglovesegfaultyeah idk how it play out, just seemed like something fun to try 04:20:24
@lovesegfault:matrix.orglovesegfaultmaybe if i used something like https://crates.io/crates/sdd04:24:06
@lovesegfault:matrix.orglovesegfault oh, hadn't seen this one before nix: ../canon-path.cc:82: void nix::CanonPath::push(std::string_view): Assertion c != "." && c != ".."' failed.` 04:27:49
