C++ - 2018 Update1/Update2 broken with CentOS7 devtoolset-6/devtoolset-7

We have the following test case. It compiles and runs normally on CentOS7 with Intel PSXE 2018 and devtoolset-6/devtoolset-7. In PSXE 2018 Update1 or Update 2, the same code compiles, but is broken. If, in Update1 or Update2, the code is compiled with -O1, it no longer fails:

$ cat test.cpp 
#include <string>

std::string a() {
return "aaa";
}
std::string b() {
return std::string("bbbbbbbb") + std::string("c");
/* return std::string("bbbbbbb") + std::string("c"); */
}
int main( int argc, char *argv[] ) {
std::string s = a() + b();
return 0;
}

Are you using devtoolset-6 / devtoolset-7 as described?

yum install centos-release-scl

yum install devtoolset-6

scl enable devtooolset-6 "bash" or "icpc test.cpp; ./a.out"

Hi Scott,

I might not have the same system as yours. Can you please attached the problematic binary so that I can try to run on my system?

Thanks,

Viet

Sure, three attachments:

test.gcc485 (Compiled with default CentOS libraries)

test.gcc631 (Compiled under devtoolset-6)

test.gcc700 (Compiled under devtoolset-7)

Hi Scott,

I saw something in your binaries like:

 400f60:       41 8b 55 00             mov    0x0(%r13),%edx
 400f64:       8d 42 ff                    lea    -0x1(%rdx),%eax
 400f67:       41 89 45 00             mov    %eax,0x0(%r13)

These 0x0 offsets should have been resolved at final link. Not sure why they weren't 

I need to ask my lab Technician to set up an identical system to investigate it further.

Thanks,

Viet

Great, glad you were able to find something. As I said earlier, it should be pretty simple to set up an identical system. From a base CentOS 7 install, you just need "yum install centos-release-scl; yum install devtoolset-6; yum install devtoolset-7".

 

If there's anything else I can do to help troubleshoot, don't hesitate to ask. I have many users eager to see this resolved.

I was able to reproduce the issue after my team-mate setup the system and filed a bug to our developer. The internal bug number is CMPLRS-49462. I will keep you posted.

Viet,

It has been about a month since your last update, confirming you could reproduce the issue. Has any progress been made in resolving it?

Hi Scott,

As far as I see, no progress have been made yet.

Is it possible to escalate the issue somehow? I have several fully paid licenses that are supposed to receive "priority support" (unfortunately, I have an open ticket there which has not received much attention).

I will try to escalate it. Can I have the other ticket number to see what is going there as well?

It has been another 10 days, anything to report? I'm starting to have some serious problems as a result of being stuck on 2018 pre-update1.

Hi Scott,

We've identified a bug in our compiler and it's being fixed.

Thanks,

I've just installed 2018 update 3, and it seems this bug is still present. Is there an ETA on the fix for this? It has been nearly 6 months since my original ticket was opened.

Hi Scott,

The fix didn't make it in time for 18.0 Update 3 code cut off, but it will be fix in the next 18.0 update.
