[jira] [Commented] (XERCESC-1976) SIGSEGV during init on SUSE11
when LANG is unset
[ https://issues.apache.org/jira/browse/XERCESC-1976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13197596#comment-13197596 ]
toske commented on XERCESC-1976:
--------------------------------
hello.
this issue is that segmentation fault occured in iconv() API.
iconv_open() must be called with locale parameter (in this case, IconvGNUTransService::fLocalCP) before iconv() is called.
iconv_open() is called in IconvGNUTransService::IconvGNUTransService and return handle.
the handle is passed to iconv() as first parameter.
please check below before iconv() (actually wrapped as IconvGNUWrapper::iconvTo) is called at xercesc/util/Transcoders/IconvGNU/IconvGNUTransService.cpp:717
i'm afraid that i don't have environment SUSE11 ,but it seems good to add debug dump of below before
xercesc/util/Transcoders/IconvGNU/IconvGNUTransService.cpp:717.
1) is fields in IconvGNUTransService valid ?
fLocalCP (should be locale string)
fCDTo (should not be -1)
2) these parameters of IconvGNUWrapper::iconvTo is valid?
ptr, len, pTmpArr, gTempBuffArraySize
thanks.
