This sure seems like a GCC issue. In the case above, "lineno" is only defined once in utils/autosp/autosp-src/utils.h (on line 64): int lineno; In a local test, there are several other "multiple definition" errors being thrown and all of them seem like false positives as well.
NM, i see the thread on fedora-devel. I know how to fix this now.
Should be fixed in texlive-base-20190410-10.fc32, trying to build now.
