Core Dump If i do not set "LANG = C & LC_MESSAGES=C" as env var

Hi Group,

I am newb to Linux world. I have snippet of source code written in c
lang, the application use icu lib for internationalization. Now when i
set LANG=fr_FR & other locale env var and run the executable it give me
core dump, segmentation fault. The snippet code deals with writing some
temporary files which need to be read later for reading purpose with
same application.

However, when i set LANG=C in the snippet code the executable woks
properly. But i found that it requires LC_MESSAGES env var also need to
set along with LANG. So I got confused here, Can anyone tell me that
what is the relationship between these two env. variables & why the
executable gives me core dump when i set locale env. var = fr_FR ?

Thanks in advance.

Neel
