Hi team, I am a user of bash. Could you help explain this? I wrote a simple loop as following: while true; do sleep 1 echo hello done But the RSS (resident set size) continue increase. (Check by ps command) Is it possible a bug of bash? Could you please help me check it? I try on bash version 3.2.51 and 4.2.10. The result is same. -- Thuan

Re: dot gob+extglob bug
The pathexp-globignore-delim.patch seems to work as advertised. If *a matches scratch/a, for example, that's a bug in the matching code I will have to identify and fix. Yes, this is the case. Based on your reply, the examples I showed are definitely a bug. Thank you so much.
