Hi,
I get a Segmentation Fault when using the intel compiler with the Gold linker in binutils. I don't get a segfault when using g++ 4.7.2. I've tested icc 12.1.3, 13.1.1 and 14.0.0 20130728. I'm using RHEL5.
Build command line :
icc14 goldcrash.cpp -o goldcrash -B <path to gold ld> && ./goldcrash
(replace <path to gold ld> with the installation of binutils 2.23.2
goldcrash.cpp :
[cpp]
struct Simple {
Simple():m_id(0) {}
int m_id;
int getID() { return m_id; }
};
int main(int argc, const char **argv)
{
Simple s;
static __thread int lastID = -1;
if (lastID != s.getID())
{
lastID = s.getID();
}
return 0;
}
[/cpp]
Thanks!

This is still causing segfaults with icc 14.0.2 and the latest binutils 2.24. I've had no reply from Intel support giving an ETA for a fix, our firm is moving to clang & gcc for development builds until this is fixed.
$ icc14 -o goldcrash goldcrash.cpp -B /spare/local/environ-infra/binutils/2.24/bin/gold -O0

Hello Richard,
I'm sorry, I don't have an ETA yet on when this is planned to be fixed. Thanks for the feedback, I will pass that along to the developers.

Hello Richard,
The developers are actively looking at this issue, although I do not yet have an ETA. There seems to be something in our direct object generation that the gold linker doesn't like. The problem can be worked around with -use-asm.

This issue is now targeted to be fixed in the next update to icc-14 (update #3), which should be available around the end of April (caveat: plans are always subject to change).

The fix wasn't checked into the v15 branch until 4/2/2014, so it's not in the initial beta release. I just checked, and it's fixed in beta update #1 (Version 15.0.0.040 Beta Build 20140428)
