Hello,
Thanks for reply,
I traced the code with print statements, I also run the script with -d
option and the debugger pointed to line
while(defined($frPage = $frPages->next)) {
which cause the segmentation fault !!!
it is very strange that this statement worked thousands of time then
cause segmentation fault !. I am afraid it is a problem of memory or
it is a bug in cpan Parse::MediaWikiDump package
any comments, tips, will be appreciated
thanks
best regards,
Motaz
