Simple program seg faults with Intel compiler

[lee218llnl]

trafficstars

A user of mine has a small test program the seg faults when compiling with the Intel classic compiler (icpc) and linking with mold. It runs OK when compiled with gcc and the new Clang-based Intel compiler.

#include <stdio.h>
#include <set>

namespace MemorySpace {

  enum MemorySpace_enum : int {
   host = 1
  };

  using type = MemorySpace_enum;

  std::set<MemorySpace::type> active_memory_spaces;

}

int main()
{
   MemorySpace::active_memory_spaces.emplace(MemorySpace::host);
   printf("WORKED\n");
}

Can you rebuild your program with -Wl,--repro and share the resulting ic19molderr.exe.tar with me? That tar file will contain all input object files so that I can reproduce your issue on my machine.

[lee218llnl]

the reproducer file is 95MB and Github appears to have a 25MB restriction. Do you have an email address that I can use to share a OneDrive link to the file? Otherwise you may need to download the Intel classic compiler and try yourself. Note that the compiler does not require a license.

[rui314]

Is it that large after compassion? If not, please try to compress it with gzip or something.

[lee218llnl]

Good idea, it was able to compress to 22MB. Please see the attached and remove the .txt extension

ic19molderr.exe.repro.tar.gz.txt

Can you try to recompile your binary with -fuse-init-array? Does it fix the problem?

[lee218llnl]

This does not appear to a valid option for the Intel compiler:

@.***:20221212_mold]$ /usr/tce/packages/intel-classic/intel-classic-2021.6.0/bin/icpc -B/collab/usr/global/tools/mold/toss_4_x86_64_ib/mold-1.7.1-x86_64-linux/bin -o ic19molderr.exe ic19molderr.C -fuse-init-array icpc: command line warning #10148: option '-fuse-init-array' not supported
