So today I discovered latest master will cause a SIGSEGV on Solaris/SPARC if FLEX_ARRAY is defined to the default value of 1. The issue is the (old) compiler I'm using from Sun doesn't pass the tests defined in 8e9739914972419baad820e76b44d9720ed885c2 (aka "git-compat-util.h: auto-adjust to compiler support of FLEX_ARRAY a bit better") so we fallback to #define FLEX_ARRAY 1. Then git-pack-objects finds something unaligned and segfaults. It always segfaults. During the deltification phase. Probably it was working on deltifying loose objects; the set I fed it was about 100 most recent objects so they were probably all loose. I'll try to track it down tomorrow. But the immediate workaround was to just add '-DFLEX_ARRAY=/* empty */' to my CFLAGS and recompile the world. This compiler accepts the empty FLEX_ARRAY macro but I'm not sure what feature test(s) would be necessary to make Git able to automatically set that, seeing as how the tests defined in 8e97 are perfectly reasonable and didn't pass. Yea, yea, shame on me for not testing Git since Nov 20th on this system... I should have caught the failure sooner. I'm buried in non-Git work these days, but will try to come up with a reasonable detection patch. Maybe someone will beat me to it. :-) -- Shawn. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
