internal error: assertion failed: remove_from_routines_list: routine not found on list (shared/cfe/edgcpfe/il.c, line 16415)

Hello, everyone,

For Boost.Python builds using ICC on Windows got error:

libs\python\src\object\enum.cpp(47): internal error: assertion failed: remove_from_routines_list: routine not found on list (shared/cfe/edgcpfe/il.c, line 16415)

          object auto_free(handle<>(mod));
                 ^

compilation aborted for libs\python\src\object\enum.cpp (code 4)

(original 'enum.cpp' and its ICC-preprocessed version added in attachment).

Reproduced for:
  - Boost 1.66.0.b1.rc2 builds using ICC,

not reproduced for:
  - Boost 1.65.1 builds using ICC,
  - Boost 1.66.0.b1.rc2 builds using mingw-w64 and MSVC.

Environment:

• Windows 10 x64,
• ICC 2018 Update 1,
• MSVC 2017 15.4.1,
• Windows SDK 10.0.16299.15,
• mingw-w64 x86_64 7.2.0,
• Boost 1.66.0.b1.rc2.

Best,

Alexander

Thank you for reporting this. I have reduced it to the following code (which only fails on Windows):

namespace boost {

extern "C"
void foo()
{
   void auto_free(int);
}

}

It seems to be a problem with a block scope declaration inside an extern "C" routine which is inside a namespace.

I have submitted this in our internal compilers database as cmplrs-47253.

After moving to IPSXE 2018 Update 2 error not reproduced. Thank you for fix!

Best,

Alexander
