'gem' command broken in 1.9.3p327

[jmthomas]

On a clean Windows XP system I first installed Ruby 1.8.7p371. I then install Ruby 1.9.3p327. I updated my path to point to the 1.9.3 installation. When I type 'gem list' I get:

C:\Documents and Settings\jmthomas>ruby -v
ruby 1.9.3p327 (2012-11-10) [i386-mingw32]

C:\Documents and Settings\jmthomas>gem list
C:\Ruby193p327\bin\ruby.exe: [BUG] Segmentation fault
ruby 1.9.3p327 (2012-11-10) [i386-mingw32]

@jmthomas have you verified the troubleshooting page?

https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-dep_segfault

[jmthomas]

I'm running the Desktop version of Windows XP SP 3 so I don't think it applies. Plus I was able to successfully install other versions of Ruby. Am I the only one reporting this?

I verified my Windows has the Opt-in setting: "Turn on DEP for essential Windows programs and services only"

[luislavena]

@jmthomas yes, you're the only one seeing this.

Please verify that other background process is not affecting process loading. things like FRAPS or Microsoft detours affect it.

[luislavena]

@jmthomas have you tried from the troubleshooting page the minimum example?

ruby -rdigest/sha1 -e "puts Digest::SHA1.hexdigest('hello')"

That fails too?

[jmthomas]

That fails too. I can't launch 'irb', can't do a 'gem list', can't run ruby. About the only thing that works is 'ruby -v'. I don't know what FRAPS is or Microsoft detours but I don't see those in the Task Manager process list. I installed 1.9.3p327 on another machine and it fails there for the same reason as shown above. All other patch levels of 1.9.3 work on that machine as does 1.8.7. Not sure what it is about 1.9.3p327 that is totally broken for me. As it stands I'm just sticking with 1.9.3p286 as I don't know of any bug fixes in 327 that I need.

[luislavena]

@jmthomas this works for pretty much everybody.

FRAPS and detour are ways to hack loading of DLLs, which could be affecting your system because there is some other software there.

Without us knowing more details of your environment, we are unable to help you further.

If you find more information please open a bug report at Ruby itself, as described in #39
