Re: [perl #131889] Segfault / malloc errors testing Uzu with latest Rakudo

2017-08-14 Thread Bart Wiegmans via RT 
Hang on, it's only MVM_JIT_DISABLE sensitive on my branch (even-moar-jit).
It appears to happen within the perl6 extension opcodes.

It's a bus error that goes away with MVM_JIT_DISABLE.
This is going to be interesting.

Re: [perl #131889] Segfault / malloc errors testing Uzu with latest Rakudo

Can reproduce, thank you!

This also requires the following modules:

JSON::Fast (broken test on my machine, but may be for any reason)
File::Temp
HTTP::Server::Async
HTTP::Server::Router
Test::Output
Template::Mustache
YAMLish

(I'm going to guess some of these were installed by rakudo star)

Arguably, we should have more of a 'batteries included' approach to a
rakudo release.

It's a bus error that goes away with MVM_JIT_DISABLE.
This is going to be interesting.

Update: Uzu has been updated to remove parallelism in order to work around the 
crash. To reproduce the issue, check out commit 6e0997d:

Other memory errors sometimes appear instead, e.g.:


moar(63339,0x7b4a6000) malloc: *** error for object 0x7fa57da56e00:
double free
*** set a breakpoint in malloc_error_break to debug


moar(63470,0x76845000) malloc: *** error for object 0x7ff9dfdbd290:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug


$ perl6 --version
This is Rakudo version 2017.07-148-g5fcce6732 built on MoarVM version
2017.07-382-g348b4262
implementing Perl 6.c.


Might be related to #131888; I see that error occasionally as well. I am
running Mac OS X 10.12.6.
