the assumption that GTF_ICON_STATIC_HDL refers to static fields is incorrect.

In this particular case (System.Char.get_Latin1CharInfo), the static handle is address of the following byte array in

else if ((idFlags == GTF_ICON_METHOD_HDL) || (idFlags == GTF_ICON_FTN_ADDR))
{
targetName = emitComp->eeGetMethodFullName((CORINFO_METHOD_HANDLE)targetHandle);
}

that suggests that GTF_ICON_FTN_ADDR does not necessarily correspond to CORINFO_METHOD_HANDLE

Marking this as 5.0 for now, although since it appears to only be for display, not a Release mode functionality issue, we can easily move it to Future.

Thanks for the analysis. Looks like it got introduced by my change in #38671. We can move it to Future because I want to make sure we still catch GTF_ICON_STATIC_HDL and GTF_ICON_FTN_ADDR cases.

GTF_ICON_STATIC_HDL and GTF_ICON_FTN_ADDR can't be converted
to names using eeGetFieldName and eeGetMethodFullName, respectively.
So, just print out the type of the target.
