No I have not gotten to 4.2.1 yet. I have experimented using j values ranging from 16 to 64. The majority of the testing is with -Otarget. But I have tried all of them.

Assuming you determine the behavior exists even in version 4.2.1, please provide more details. What level of -j are you using? Which sync mode are you using? Do you get the same behavior even with lower levels of -j, if yours is very large? _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
