https://d.puremagic.com/issues/show_bug.cgi?id=11684 I'm afraid you'll have to git bisect to find out when this started happening. I've been compiling medium-sized projects with git HEAD and everything runs without any problems, so my environment isn't useful to track down this problem. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

https://d.puremagic.com/issues/show_bug.cgi?id=11684 Interesting. The segfault is caused by stdout being null. But std.stdio's static this() does initialize it correctly. So the static this() somehow isn't getting called by the druntime startup code??? What compile flags are you using, and what's the contents of dmd.conf? -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

The .ctors .dtors sections of the object files are truncated, they are 4 byte each, but they should be 8 byte for the 64-bit pointer.

https://d.puremagic.com/issues/show_bug.cgi?id=11684 Seems like changing the relocation at this line fixes the problem. https://github.com/D-Programming-Language/dmd/blob/2a589a19cbd7e95880653043ebb556bf214b8340/src/backend/elfobj.c#L3436 `reltype = (config.flags3 & CFG3pic) ? R_X86_64_64 : R_X86_64_32;` always use R_X86_64_64 `reltype = R_X86_64_64;` I'll still have to see why this didn't fail on other platforms.

Before this commit the code still wrote out an 8-byte address, so the zero extension worked happened to work for <4GB binaries. https://github.com/D-Programming-Language/dmd/commit/e8d0efc8ea7c2fe35f859dd5dce486b5361ae1ed [2.065,Reg] fix Issue 11684 - SIGSEGV with ld.bfd version 2.22 -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I don't know which distributions are running on the auto-tester. But even if we threw 10x more machines on the problem there will always remain some configurations that don't get tested.
