Bash Version: 4.2
Patch Level: 45
Release Status: release
Description:
When using \w in the prompt and changing the directory outside of HOME
bash crashes with an abort trap.
strcpy(3) say src and dst must not overlap. OS X 10.9 checks that on
runtime and forcefully aborts your code if they do.
Repeat-By:
PS1="\w"
cd /
bash exists with an abort trap.
Fix:
Assign the return value from polite_directory_format to a temporary value.
If the pointers are different and only then do a strcpy
