When we run Psalm in one thread it works as expected:

$ vendor/bin/psalm --show-info=false --threads=1
Scanning files...
Analyzing files...

------------------------------
No errors found!
------------------------------

Checks took 20.19 seconds and used 852.012MB of memory
Psalm was able to infer types for 92.7393% of the codebase

However, when running in more than one, we see fatal errors:

This is a private, commercial project, so I'm unable to share the code to aid in debugging, but if there's anything else I can run to get more useful information, please let me know.

Thanks for making Psalm, it's a fantastic tool and has helped improved our code quality massively.

Do things still break if you run with --no-cache?

Yeah, the output is exactly the same when run with --no-cache.

Mind running with --debug to see what files it crashes on?

I am experiencing the same issue, and am in the same boat with the closed source codebase :-/

Here is what i get from the last few lines of output with ./vendor/bin/psalm --show-info=false --threads=2 --debug

Interestingly, the last letter is missing from the path to my codebase in number 4

The last one was for version 3.2.2. With version 3.2.10 and using ./vendor/bin/psalm --show-info=false --threads=2 --debug --no-cache I get

Signal 11 is SIGSEGV, so Psalm managed to crash PHP somehow.
Inspecting core dump might help, you can find instructions on how to make php dump core here: https://bugs.php.net/bugs-generating-backtrace.php
There's a bunch of useful gdb macros available in php-src repo: https://github.com/php/php-src/blob/master/.gdbinit

I've just added some extra debugging for the scanning step to latest master.

What platform are you running on?

@ylixir
Copy link

ylixir commented May 7, 2019

Mac OS with PHP version 7.2.17 from Nix.
Happens with or without Xdebug
Upgrading to 7.3.4 or downgrading to 7.1.28 causes the same issue.

I don't see any core dumps in my home directory or my project folder. I'll poke around later and see if I can get a proper core dump.

What do you see when you use latest master with debug flag turned on?

I've tried with the latest Psalm master branch and still see the issue. I've included a dump of a run with --debug enabled.

@jaikdean I'm sorry this is happening - would you be able to add some var_dumps in Scanner::scanFile to try to narrow down where the segfault is happening?

@andrew-demb are you getting a crash too? Or are you just looking at the code?

I don't have the bandwidth fiddle with master today. I will turn multithreading on in circle-ci and see if I can reproduce in Linux while i'm working today. If so I'll give you the name of the docker image we are using.

Just looking.

I met similar errors (not sure about core dumps) about two months ago and just not using threads.
Now I cannot reproduce a problem in my projects.

After much digging, I've tracked this down to an issue with PHP 7.3's PCRE2 and appears to be related to this issue with Homebrew's installation of PHP, with some more detail here.

Setting pcre.jit=0 in php.ini resolves the problem for now.

Thanks!

Psalm now prevents threaded execution if pcre.jit=1 is detected on macs running PHP >7.3.
