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.

FWIW in Percona Server we migrated from std::regex to my_regex because of GCC 4.8. I can dig up the commits if you wish
This is not about just one query. First 80 lines of the test pass, but the rest 110 lines are all crashes or failures.
