 Such an issue was fixed once before in MAME (two years ago):

 https://git.redump.net/mame/commit/?id=d95c5b097ae118d66f8f3b6a9439403713e7d718

 so I would guess some compilers (such as the version of clang you happen
 to be using, which is different from the version of clang we are using on
 our build servers) are more picky about whatever this is than others.

 This commit made a couple weeks ago looks relevant:

 https://git.redump.net/mame/commit/src/lib/netlist/plib/pmatrix2d.h?id=c60cc01dbc1ac362cd5af940f5abf6bad549f8f9

 Does applying this patch fix the problem for you? If so, we can add it to
 the port.
