Hi, in order to fix the problem you need to comment one line
in X11_GX11Gui.cxx file:
void TGX11::FreeFontStruct(FontStruct_t fs)
{
// Free font structure returned by GetFontStruct().
// XFreeFontInfo(0, (XFontStruct *) fs, 1);
}
The XFreeFontInfo call SHOULD be commented. I've fixed described problem in
this way and reported already for ROOT mainteiners at CERN/FNAL.
Ths problem appears since the new version of XFree-v4 has different
meaning of XFreeFontInfo. I'll recomend all of you to recompile your
root package. For my station (RedHat 6.1 with XFree v4) the problem
disappeared.
Valentine.
