DMD ICE: Can't link simple program with `-profile=gc`

[MrcSnm]

import std.path;
void main()
{
	buildPath("tester", " a");
}

Tested with run.dlang.io with All Compilers. Looks like that program never was able to build.

That was causing ICE on my program which has multiple cases of that.

I also get that at the reduced example:

/dlang/dmd/linux/bin64/../../src/phobos/std/array.d:1112: error: undefined reference to '_d_newarrayUTrace'
collect2: error: ld returned 1 exit status
Error: undefined reference to `_d_newarrayUTrace`
       perhaps a library needs to be added with the `-L` flag or `pragma(lib, ...)`
Error: linker exited with status 1

Are you sure that you copied the code correctly? I just tried it both locally and on run.dlang.io with All Compilers, and it worked just fine.

EDIT: Nevermind. I missed the -profile=gc in the title. It does happen when I add that.

cc @teodutu this looks like something you might know about.

Yup, in #15299 I converted _d_newarrayU to a template, but I only created a trageCG wrapper for _d_newarrayT because I only saw that being used in the tests. I can create _d_newarrayUTrace and fix this issue next week. I'll also look into _d_newarraymTX #15819 and make sure it doesn't suffer from this as well.
