peglint crashes

[mqnc]

Hi!

Somehow peglint does not work for me like described in the readme:

$ cat a.peg
Additive    <- Multitive '+' Additive / Multitive
Multitive   <- Primary '*' Multitive / Primary
Primary     <- '(' Additive ')' / Number
Number      <- < [0-9]+ >
%whitespace <- [ \t]*

$ ./peglint --ast --source "1 + 2 * 3" a.peg
terminate called after throwing an instance of 'std::system_error'
  what():  Unknown error -1
Aborted (core dumped)

When I run in server mode, it shows the page and then crashes:

$ ./peglint --ast --server 8001 --source "1 + 2 * 3" a.peg
Server running at http://localhost:8001/
(now I open the browser and it shows a promising page)
terminate called after throwing an instance of 'std::system_error'
  what():  Unknown error -1
Aborted (core dumped)

I compiled and ran under Ubuntu,
The C compiler identification is GNU 7.2.0
The CXX compiler identification is GNU 7.2.0

All the best!

PS: If you can't reproduce this, I can try to provide more debug information.

@mqnc, thanks for the report. But I don't reproduce it. Here is my result:

$ ./peglint --ast --source "1 + 2 * 3" a.peg
+ Additive
  + Multitive
    + Primary
      - Number (1)
  + Additive
    + Multitive
      + Primary
        - Number (2)
      + Multitive
        + Primary
          - Number (3)

What happens with $ ./peglint a.peg in your environment? (It's supposed to show nothing which means there is no syntax error in a.peg.)
Thanks!

It happens on travis consistently for me too. I don't have the exact g++ version, but travis is repeatable.

I setup Ubuntu 18.04 Server. I am now able to reproduce it. I'll take a look at it when I have time.

@fire, I found that this problem is caused by the same reason as as the #23. Also this stackoverflow post explains the problem very well.

I updated lint/CMakeLists.txt to link pthread at 469a61f, so could you build peglint and test it again? If it works in your environment, I'll close this issue. Thanks for your help!

Thank you, now it works properly!
