Bug #6616: MinGW: cannot build extensions or run tests due changes in exec_arg?

• Status: Closed
• Assignee: akr (Akira Tanaka)
• Target version: 2.0.0
• ruby -v: trunk r36158

[luislavena (Luis Lavena)]

Hello,

Originally reported in [ruby-core:45727] due Redmine being down.

Latest trunk revision (r36154) is failing on me:
https://gist.github.com/2959908

Decided to attempt a Git bisect to determine the commit that
introduced this and which doing it found another error at r36148:
https://gist.github.com/2960374

Worker machine as 4GB of RAM (Windows 7 x64) and memory was no
exhausted during tests (monitored memory usage)

Git bisect didn't tell me precisely which commit failed since the
error happens randomly except for last commit, which happens always.

Build was made on a separate directory (build32) inside Ruby's source.

MinGW GCC 4.6.3 was used (mingw-w64) which has build successfully
everything in the past.

Entire work tree is reset on every build.

I can attribute this issue to support libraries or compiler since
those have been the same and work properly in the past revisions and
also against ruby_1_9_3 branch.

Further investigation shows the following:

configuring digest/md5
wrong argument type false (expected exec_arg)
Failed to configure digest/md5. It will not be installed.
configuring digest/rmd160
wrong argument type false (expected exec_arg)
Failed to configure digest/rmd160. It will not be installed.
configuring digest/sha1
wrong argument type false (expected exec_arg)
Failed to configure digest/sha1. It will not be installed.
configuring digest/sha2
wrong argument type false (expected exec_arg)
Failed to configure digest/sha2. It will not be installed.
configuring dl
wrong argument type false (expected exec_arg)
Failed to configure dl. It will not be installed.

Which might indicate an incompatible change with exec?

[phasis68 (Heesob Park)]

Here is a simple code for the cause of this issue.

C:\work>ruby -ve "system('dir')"
ruby 2.0.0dev (2012-06-21 trunk 36156) [i386-mingw32]
-e:1:in system': wrong argument type Object (expected exec_arg) (TypeError) from -e:1:in '

This bug is due to the revision r36152.
I guess the revision r36152 is untested or unfinished.

I doubt this is a GC problem.

At least current trunk has a problem as follows.

Bug #6616: MinGW: cannot build extensions or run tests due changes in exec_arg?

Latest trunk revision (r36154) is failing on me:
https://gist.github.com/2959908

I doubt this is a GC problem.

At least current trunk has a problem as follows.

boron% ./ruby -e 'GC.stress = true; eval("def m(k: 0) end")'
-e:1: [BUG] iseq_compile_each: unknown node: NODE_ARGS
ruby 2.0.0dev (2012-06-21 trunk 36158) [i686-linux]

nobu fixed the GC problem at r36161.

I hope that the revision also fix this issue.

I think r36161 is not related with this issue.
After applying r36161, this issue is not fixed.

This compile time message is very helpful.

Apologies, I missed the compilation warnings from the worker computer.

I hope r36165 fixes this issue.

Seems to have fixed it, will close the bug report.
