Hi, In bash 5.1 we're seeing a parallel make race during build, as found a couple of times in our automated CI for Yocto Project:
https://autobuilder.yoctoproject.org/typhoon/#/builders/80/builds/1720/steps/14/logs/stdio https://autobuilder.yoctoproject.org/typhoon/#/builders/44/builds/2969/steps/25/logs/stdio The issue is around pipesize.h which in 5.1 can be built by two different triggers, builtins/ulimit.o or redir.o. They can race against each other and rewrite files causing the above failure. We added a bit of a hacky workaround: Index: bash-5.1/Makefile.in =================================================================== --- bash-5.1.orig/Makefile.in +++ bash-5.1/Makefile.in @@ -746,7 +746,7 @@ ${DEFDIR}/bashgetopt.o: $(BUILTIN_SRCDIR ${DEFDIR}/builtext.h: $(BUILTIN_DEFS) @(cd $(DEFDIR) && $(MAKE) $(MFLAGS) builtext.h ) || exit 1 -${DEFDIR}/pipesize.h: +${DEFDIR}/pipesize.h: $(BUILTINS_LIBRARY) @(cd $(DEFDIR) && $(MAKE) $(MFLAGS) pipesize.h ) || exit 1 $(SDIR)/man2html$(EXEEXT): ${SUPPORT_SRC}/man2html.c Cheers, Richard
