But you examined the stack ? It's similar to mine ?
#0 0xffffe410 in __kernel_vsyscall ()
No symbol table info available.
#1 0xf76539cb in poll () from /lib/libc.so..
#2 0xf770d39a in pqSocketCheck () from /home/pg/pgsql/lib-32/libpq.so.5
#3 0xf770d49d in pqWaitTimed () from /home/pg/pgsql/lib-32/libpq.so.5
#4 0xf770d513 in pqWait () from /home/pg/pgsql/lib-32/libpq.so.5
#5 0xf770c6d6 in PQgetResult () from /home/pg/pgsql/lib-32/libpq.so.5
#6 0xf770c89c in PQexecFinish () from /home/pg/pgsql/lib-32/libpq.so.5
Can you specify the details of hardware and platform of your machine to understand if it can have something in common with the mine and so to understand the reason/origin of the bug?
Thanks.
