Bug #9289

Segmentation fault - RailsInstaller, RubyInstaller, Ruby.

Added by bob (bob barker) about 7 years ago. Updated over 1 year ago.

Target version:
ruby -v:


Installed RailsInstaller; Ruby crashes it on post-install config (ssh/git). Confirmed by running ruby with no params and crashes.
Downloaded various versions of Ruby from RubyInstaller project (as 7z's) - latest version to not crash on running ruby.exe was:

moves up past that in version number crash i.e. ruby-1.9.3-p327-i386-mingw32
oddly enough, can run ruby --version on all the later ones without it crashing

This type of crashing sometimes is associated with other tools that is affecting loading of DLLs.

Can you verify if you have installed ansicon or FRAPS? Also, can you tell us which Antivirus software you have installed?

Thank you.

Updated by bob (bob barker) about 7 years ago

Neither Ansicon or FRAPS is installed. I am using the free edition of ZoneAlarm Firewall+Antivirus. To get the rails-installer to finish its config work, I replaced the p484 version with p286 version after it installed but before I hit next for it to complete its ssh/git configs. Latest version of JRuby is also installed in case it makes a difference.

This issue is an unresolved issue with a long history.

I guess it is related with the encoding of file system according to the ChangeLog of 1.9.3-p327.

How can I reproduce your issue?

Can you show the environment variables like PATH, HOMEPATH, RUBYOPT, RUBYLIB, TEMP etc which might be contain non-ascii value?

Updated by bob (bob barker) about 7 years ago

You can't ;) I can - what sort of trace would you need to tell exactly what its crapping out on (i.e. debugging the startup of the interpreter?); Would building the files rather than using the installer and comparing (i.e. checking of the locally-compiled version) crashes help? Sort of determining if the problem is in the source versus the distro (compilation params)? I am at your service.

The gdb(the GNU debugger included in DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe) trace information would be helpful.

Refer to for how to produce it.
