nvidia-settings 290.x segfaults when running GUI

Hi,

some time ago, maybe starting with 290.x, nvidia-settings segfault when run without any command line options. Running command line queries (e.g. -q all) works however.

The backtrace (from self-compiled nvidia-settings 290.06):

In case it matters, glibc version is 2.14 git-2011-09-29.

Let me know if there's any other information I can provide. Thanks.

The forum doesn't allow me to attach a core dump (1.8M bzipped). Let me know how/where to upload it, if you need it.

One more data point: if running it under valgrind, it doesn't segfault (but obviously runs very slow).

I re-compiled glibc with this patch http://www.linuxfromscratch.org/patc...-fixes-1.patch, and nvidia-settings is no longer crashing.

After googling a lot, it appears this is a known issue, and nvidia-settings isn't the only affected application. However, no fixes has appeared upstream yet (at least not in the 2.14 branch). So, I'm not sure if this is considered a bug or a "feature" (i.e. an application bug) from the glibc devs' perspective.

@dae thanks for finding this patch - works great. It fixed segfault in my nvidia-settings 290.06 on Lunar-Linux with glibc 2.14.1.
