Summary: XQ: algebra queries have 7 lives
Initial Comment:
The current nightly build (2008-04-29, from SuperSourceTarBall with 64bit-oid)
gives you roughly 7 tries before MonetDB with "--set xquery_backend=algebra"
stops with a "Segmentation Fault"
It seems that this holds for any query, but some queries have more lives. A
query '<aap/>' has about 7 lives. A 'concat("duck","cow","horse")' together
have about a hundred lives. A query 'doc("rabbit")' can be executed about 5
times before the database crashes. It also seems to depend on the rate of
executing queries. The system will crash quicker, if queries are fired at the
database at a high rate.

Hi Wouter,
Thank you for the bug report. There was a similar bug report yesterday [
monetdb-Bugs-1953446 ] Segmentation fault on pathfinder/algebra --
mclient/G and was fixed today. I don't know if it is the same problem, but
since you used a yesterday's build, probably it was. I repeated the queries
on todays cvs head, multiple times and I did not get any segmentation fault
so it seems that it was the same bug. I will close this bug with a
resolution duplicate.
