I was able to reproduce this error on centos 6.5, when having a 24 MB
/etc/sysconfig/nfs configuration file, any tool using augeas-libs just
broke with segmentation fault.
Using augeas-libs-1.0.0-5.el6_5.1.x86_64
Fixed just trimming down the faulty configuration file as a workaround.
Reproduced easily just appending data into the file until it's big
enough (17 MB was enough for me). It does not matter if you add real
configuration entries or just comments.
This is what I used to test it:
for i in $(seq 100); do echo #WHATEVER=NOTHIG /etc/sysconfig/nfs;
done
After that running augtool:
# augtool
Segmentation fault
With gdb:
# gdb augtool
