toske commented on XERCESC-1976:
--------------------------------
perhaps the problem is solved because IconvTransService.cpp does not uses iconv
API (it uses ANSI wcstombs function).
i tested the case that uses gnuiconv and unset LANG on Ubuntu10.10, but it did
not crash and parameters of iconv was valid. if LANG variable is unset,
character code is set to default iso-8892-1 (Latin-1).
> SIGSEGV during init on SUSE11 when LANG is unset
