--- Comment #24 from Dimitry Andric <d...@freebsd.org> --- (In reply to Alexandre Ganea from comment #23) This is the tricky part! I've only been able to reproduce this problem until now within the FreeBSD build system. That is, the result of one particular file being compiled is dependent on whether make is running with or without -j (and in some cases, the value of the -j option). As of now, I can "fix" the problem by using #define CLANG_SPAWN_CC1 1 in lib/clang/include/clang/Config/config.h, which effectively disables the in-process cc1 by default. At least then you always get the same object file output. But as to *why* the result differs when CLANG_SPAWN_CC1=0, and being invoked under different variations of make or make -j, it is not clear yet. One thing which Bryan Drewery just mentioned on IRC is that make -j messes with stderr, causing it to no longer be a tty. I think that must have some sort of influence, but it's going to be tricky to debug (especially if you want to send debug output to stderr :). -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
