This is the same as bug 883611, I think. It's a race. Arsen wrote a patch at https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-devel/reflex/files/reflex-20230206-parallel-build.patch?id=5f14870405eb92a33d12a55c38fa67ffe93b9a86. I think he sent it upstream but I'm not sure (it was a little while ago now so long paged out..)
thanks for the reminder (I haven't been able to reproduce the race directly, only seen it second-hand as in this report).
The suggested patch doesn't appear to introduce new problems (may fix this case). I think that part of my difficulty in reproducing it is that my usual development machines don't have enough CPUs. Trying the patch directly on a more powerful machine doesn't show a problem. However (noting Arsen's comment about not handling failure in mkscan.sh), if I force that script to fail, then even with this patch I get build-failures similar to this case. I'll investigate and see if I can improve this.
Thanks! It took me quite a few tries as well. I think I could hit it more often with distclean first, but I'm going off memory. There is a fast arm64 machine with a lot of cores you're welcome to use (on an ongoing basis for general work) if you're ever interested (there's also other arches too but they're not so fast).
Created attachment 862352 [details, diff] add dependency to fix race Adding a dependency forces the make program to process the rules in the order given (seems to work with 6-core machine).
fixed upstream https://invisible-island.net/reflex/NEWS.html#t20230523 2023/05/23 + modify configure script and makefile to comment-out actions which run the generated program if it is cross-compiled. + add dependency to "scan.c" rule in makefile to eliminate a race with the ".bootstrap" target (Gentoo #906965).

Thank you! I indeed can't reproduce it anymore. Fingers crossed :)
