Description:
On 'vm-win2003-64-b' Win64 VS2005 -max-nt the test 'max_heap_table_size_basic_32' seems to fail due to a bug in the server. Assumed reason is a 32-bit build on 64 bit machine which might not be implemented well. Means the behaviour of the system variable depends on the machine and not on the build. I am nor sure if variables in a 32 bit build may get 64 bit values. See following excerpt of log:
main.max_heap_table_size_basic_32 [ fail ]
