How do I recover from upgrading while using bad version of gcc/binutils?
- by Shawn J. Goff
I upgraded from 9.04 to 10.10 a couple of days ago, and things are really messed up - X is crashing constantly.
Since then, I had an application segfault for no reason, when I was debugging, I found that it was strlen() that was causing the segfault (pointing to libc being the problem)! Upon investigation, I found that it was because I had a bad version of gcc and binutils installed in /usr/bin/local; I removed it, recompiled the application, and it no longer crashes.
Now, looking at my logs, I see that X is also crashing due to libc.

So, how can I recover from this?
