segmentation fault in sockets library of sicstus prolog

#1 07-23-2008, 09:42 AM

Hi all,

I am using the linda library in sicstus prolog 4.0.4 for
commmunication between processes.

The linda server is calling the predicate socket_select/7 which
sometimes gives segmentation fault and I could trace the error to this
particular line in socket_select/7:

prolog:'$select'(ListenSocketsRaw,LReadyRaw,
ConnectSocketsRaw,CReadyRaw,
ReadStreamsRaw,RReadyRaw,
WriteStreamsRaw,WReadyRaw,
TimeoutParam, ECODE)

I could further find out that ultimately this call is making a system
call select but I could not find out what happens in between.

Could anyone of you tell how to fix this or where does the control go
after you make a call to prolog:'$select'?

Thanks,
Pragyesh

If SICStus Prolog gives a segmentation fault then it is a bug. The
best way to resolve SICStus bugs is to report them at the SICStus
Prolog home page (www.sics.se/sicstus/ under "Support").
