clang (10.0.0 is fine BTW) will warn about this anyway on CI.
For the debug build gcc10:
- before patch:
- concat.cpp -> >5m (stuck on cc1plus, not as)
- has.cpp -> >10m (stuck on cc1plus, not as)
- after this patch:
- concat.cpp -> 1m16s
- has.cpp -> 4m (and most of the time eats, as from binutils 2.34.50.20200508)
Command for build:
- ninja src/Functions/GatherUtils/CMakeFiles/clickhouse_functions_gatherutils.dir/concat.cpp.o
- ninja src/Functions/GatherUtils/CMakeFiles/clickhouse_functions_gatherutils.dir/has.cpp.o
The test case should be reduced and then it can be reported to the gcc
bugzilla.
P.S. Looks like a signal not to switch to gcc10 for now
