Re: [Nano-devel] Nano 1.3.8 and 1.3.8-cvs crashes on suse 9.3 x86_64

[Jan Jitse Venselaar]

Hello, 

I'm also experiencing the same problem (same glibc patches, same crashes), and 
I might have gotten a more useful valgrind check. Also note that it crashes 
regardless of optmization, the following reports are made with CVS of today, 
with CFLAGS="-g3". I'm wondering if you could take a look at this, and say if 
the problem is really within nano, or maybe it's in the patched glibc which 
I'm beginning to suspect.

valgrind report attached

Hope you can help, otherwise could you point me to some resource which will 
help me understand the source of these problems?
