Query (0x7f10c800ef90): SET GLOBAL rocksdb_strict_collation_exceptions=",s.*,t.*"

This is because of GCC.
The upstream solves it as follows: collation.test has --source include/have_fullregex.inc
which has this contents:
# Skip test if we didn't compile with a compiler that supports full regex
|
# Currently only gcc is tested (gcc 4.9 is the first version to support full
|
# regex). All other compilers are assumed to support it.
|
# Add further checks as we get information on these compilers
|
|
|
--disable_query_log
|
set @comp_version = @@version_compile_compiler_major * 100 +
|
@@version_compile_compiler_minor;
|
set @is_gnu = STRCMP(@@version_compile_compiler, "GNU") = 0;
|
--enable_query_log
|
if (`SELECT IF (@is_gnu, IF (@comp_version > 408, 1, 0), 1) = 0`)
|
{
|
--skip Test requires full regex (not supported in gcc 4.8 and prior)
|
}

- MariaDB doesn't have @@version_compile_XXX variables, so we can't re-use this approach directly.
- We can disable MyRocks on gcc-4.8, but this seems like an overkill.
- Or we could disable the query.
Not sure which one is better.
