Sorry, I was hand-typing from an air-gapped network. I left the type name
out; line 5 should read:
> thread_local int mything = 3;

This doesn't compile for me:
pr85400.C: In member function 'int Test::blah(int)':
pr85400.C:5:18: error: 'mything' does not name a type
thread_local mything = 3;
^~~
pr85400.C:6:5: error: 'mything' was not declared in this scope
mything = y > 0 ? y : mything;
^~~

Do you have local patches? My compiler is the stock GCC 8.x:
Using built-in specs.
