Bug #6391: Segment Fault while execute make_encmake.rb for Ruby 1.9.3 P194 ( MinGW64)

• Status: Closed
• Assignee: nobu (Nobuyoshi Nakada)
• Target version: -
• ruby -v: ruby 1.9.3p194 (2012-04-20) [x64-mingw32]

[[e-mail] (ray linn)]

The Ruby is compiled by MinGW64 (GCC 4.7.0 ), configure script is :

./configure --build=x86_64-w64-mingw32 CFLAGS="-O2 -mieee-fp -I/usr/local/include" LDFLAGS="-L/usr/local/include"

when miniruby executing, error occurs with the following message:

    CC = gcc
    LD = ld
    LDSHARED = gcc -shared
    CFLAGS = -O2 -mieee-fp -I/usr/local/include
    XCFLAGS = -include ruby/config.h -include ruby/missing.h -fvisibility=hi

Hello,

Are you trying to build trunk? GCC 4.7.0 changes hasn't been backported yet to ruby_1_9_3 branch

There is no mention of revision against you tested it.

Please confirm.

[[e-mail] (ray linn)]

Here is the update:

1. I renamed my folder local to local.old, so that any 3rd partt lib will not be linked.
2. Rolled back GCC from 4.7.0 to 4.6.2.
3. just use the following command to configure : ./configure --build=x86_64-w64-mingw32 CFLAGS="-Ox" x will be replaced as 2 or 3.

after took all these actions, I got the following result:

1. Ruby 1.9.3P0 x=3 passed; x=2 failed
2. Ruby 1.9.3P194 x=3 passed; x=2 failed
3. Snapshot {ruby 2.0.0) x=3 passed; x=2 failed.

[phasis68 (Heesob Park)]

I can reproduce this issue for trunk with MinGW64 4.7.0 on Windows 7.

I found it is related with inline function optimization.

Here is a workaround:
./configure --build=x86_64-w64-mingw32 CFLAGS="-O2 -finline-functions"

[[e-mail] (ray linn)]

that means even choose -O0, still could see this issue. could it be duplicated on Linux?
