Changeset: 8a0f93f6bfe1 for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB/rev/8a0f93f6bfe1
Modified Files:
gdk/gdk_join.c
Branch: Jan2022
Log Message:
Use unique names for temporary hash for join.
It clashed with the name for the temporary hash for unique, however,
the chance that they would clash is exactly 0 (the thread id is part
of the name, and a thread can't do two things at the same time).
