Problem with locale and XFree86 under RedHat

[laurent.jean-rigaud@xxxxxxxxxxxxxx]

Hi,

We currently porting some applications from HP to LINUX RedHat and we meet 
a problem with locale. The problem appears with RH7.2+XFREE430, RH9 et 
RHEL3.0.

The problem is if we set a locale to en_GB, our test app seems to crash in 
XIM code. If the locale is set to en_GB.utf8 , the problem disapears...
So it is mandatory to set the locale to something UTF8 compatible ?


Here is the code for testing : it compiles with "gcc -DLINUX -g -static -o pb_label_accent pb_label_accent.c 
-I/usr/X11R6/include -L/usr/X11R6/lib -lMrm -lXm -lXp -lXext -lXt -lSM 
-lICE -lXmu -lX11 -lm"

Thanks for you help.

PS: maybe the problem come from GLIBC ?
