[Bug ld/10406] ld terminated with signal 11 [segmentation fault]
--- Additional Comments From olof at baah dot se 2009-09-18 18:31 --- Subject: Re: ld terminated with signal 11 [segmentation fault] I can try but I think you need to give me some hints. I'm not too familiar with automake & gdb. 1) How can till the configure script to insert -g in the makefiles it creates for binutils? I didn't find anything on the net or with configure --help. Or should I do it some other way? 2) Where can I read about backtrace generation? I suppose that is something gdb can provide? // Olof 2009/9/14 amodra at bigpond dot net dot au : > > --- Additional Comments From amodra at bigpond dot net dot au 2009-09-14 > 07:12 --- > Yes, the error may well only occur when ld is linking non-gcc object files. > Regardless, ld should not segfault.

No great success, the latest cvs doesn't buid, at least not on my system.

sysinfo.o:/usr/local/src/src/binutils/sysinfo.c:1: first defined here
Both of these files contain "main() { return 0; }"
Want me to try the .19 sources with some patch?
