Compilation error with hip-clang with debug symbols

[davidrohr]

The attached test-case fails if I compile it with hip-clang with debug symbols.
I followed the recipe from #1196 to build hip-clang (based on ROCm 2.7 installation).
Some points I already found out:

• The error appears only when the GPU code is in a shared library which I open with dlopen, if I put the GPU code in the executable or if I link to the library directly, it works.
• The problem appears only when I set the -g debug settings on the command line.
• The error appears only when the kernel has that empty shared memory object, although it is not used.
• The failure does not appear with hcc as HIP_COMPILER, only with clang.

  The failure shows up as the following gdb stacktrace:

terminate called after throwing an instance of 'std::exception'
  what():  std::exception

[davidrohr]

I have retried with the current amd-common branch of clang / llvm and the error is gone.
Closing this.
