Bug 10274 – DMD 2.063 produces broken binaries

Posted at the newsgroup http://forum.dlang.org/thread/87fvwx3g8o.fsf@wyvern.i-did-not-set--mail-host-address--so-tickle-me. Hi folks, I've downloaded the current dmd 2.063 zip and tried it out. This is Ubuntu 12.10 x86_64. Every program I compile segfaults when I try to run it. As a simple example: jlquinn@wyvern:~/re/test$ cat junk.d import std.stdio; void main() { writeln("Hi"); } jlquinn@wyvern:~/re/test$ /home/jlquinn/dmd2/linux/bin64/dmd junk.d jlquinn@wyvern:~/re/test$ ./junk Segmentation fault (core dumped) The gdb backtrace is somewhere in __libc_start_main, before main() is run. I assume I'm not in the majority, but I literally can't compile and run anything. Any help would be appreciated Thanks Jerry

I attempted to reproduce the issue as follows: 1. Downloaded Ubuntu 13.04/64 2. Installed it under VirtualBox hosted on OSX 3. In the VM, downloaded and installed 2.063 from dlang.org/download.html. 4. Created file junk.d as indicated 5. Compiled as indicated (log below) 6. Ran the resulting executable, which printed "Hi" and exited normally. This seems to be an installation issue. Jerry, could you please download again, reinstall, and recheck? Thanks!

I just pulled down a fresh copy onto my Debian testing x86_64 box and tried it there. Same issue - segfault. I'll repeat on my Ubuntu system but expect the same result. Is there a way we can compare .s files or other intermediate product? Unless there's code in the compiler that says if (user == "jlquinn") { insert segfault; } :-) Would swapping binaries be useful?

I pulled down a fresh copy of dmd 2.063 and I still reproduce the segfault on my Ubuntu 12.10 x86_64 system.

I tried Ubuntu 12.04, Ubuntu 12.10 and Debian in VirtualBox and couldn't reproduce it either. It would be helpful to know more about where it crashes. Can you gdb into the core dump and print the disassemble and backtrace. To enable core dumps use "ulimit -c unlimited" To disable them again "ulimit -c 0" Run the binary to produce a core dump. "./junk" Run gdb and get more information. "gdb junk core.<PID>" "(gdb) disas" "(gdb) bt"

I tried building dmd on my machine but irstate.h is missing from the zip file.

(In reply to comment #10) > I tried building dmd on my machine but irstate.h is missing from the zip file. No problem, I already found something. The +4 offset is wrong it should be +8 because it's the length field of rt.util.container.Array(T) and on X86_64 the pointer before it is 8 byte. <_D2rt14sections_linux12_static_dsosS2rt4util9container36__T5ArrayTPS2rt14sections_linux3DSOZ5Array+4> Also the rest of your asm slightly differs from mine. So either we're not linking against the same library or your linker rewrites code (LTO?).

Jerry reported on the n.g. that valgrind reports an "Invalid write of size 8" at: 0x0000000000438cc8 <+512>: mov %r14,-0x8(%rax)

OK, let's start with a simple thing. sha1sum /usr/lib64/libphobos2.a 40cddd5a8a9f28c000346014cbb4221a3bbd91b4 /usr/lib64/libphobos2.a

Additional data - the following gives me a working program: dmd -c junk.d copy junk.o libphobos2.a to centos6.4 x86_64 machine on centos6.4, link using gcc link line given by dmd -v junk.d

Also, the stdio bits are a red herring. The following also segfaults: void main() {}

Created attachment 1224 Crashing binary cat > junk.d void main() { } dmd junk.d This is the executable junk.

OK, can you dump the linker output? dmd junk -L--verbose
