For the 'ASAN runtime does not come first ' error, you probably need something like `LD_PRELOAD=/usr/lib/libasan.so` either exported or added before your build command. E.g., from my bash history: `ASAN_OPTIONS="detect_leaks=0"...

A month or so @coke and I were experimenting with adding locking to the implementation of ‘is cached’, but I think we never quite got a finished solution. Sent from...

I can't repro at `This is Rakudo version 2020.08.2-35-g09e4f2333 built on MoarVM version 2020.08-77-g51d399cb5 implementing Raku 6.d.` running either normally or under valgrind (both with FSA debug on).

This is not better. Now there are tons of ``` src/core/nativecall.h: In function 'MVM_nativecall_find_thread_context': src/core/nativecall.h:145:22: warning: unknown conversion type character 'l' in format [-Wformat=] MVM_panic(1, "native callback ran on thread...

I believe the leaking is (almost?) entirely because the loop is finishing before any garbage collection happens. So if you add something like `$*VM.request-garbage-collection if $_ %% 1_000` in your...

Backtraces from the error: ``` [dan@alexandria perl6]$ gdb --args ./install/bin/raku -e 'my $t = "errors.md.tmpl".IO.slurp; race for ^100_000 { my $page = $t; $page ~~ s:g[ "(only-browser(" (.+) ")only-browser)" ]...

No change with `MVM_SPESH_DISABLE=1`.

Those are doing so little work inside them that they're mostly measuring startup, which is known to be slightly slower after new-disp.

In either case, it might be useful to zip up the complete rakudo+nqp+MoarVM directories so someone can investigate. Sent from my iPhone > On Aug 6, 2022, at 4:00 PM,...

`--optimize=off` also gives the correct behavior.
