die__process_class: tag not supported 0x4106 (GNU_template_template_param) at <23490>!

Hello,

I was trying to run pahole v1.29 against the debuginfo file for Microsoft's build of OpenJDK's libjvm.so. (lib/server/libjvm.debuginfo from https://aka.ms/download-jdk/microsoft-jdk-debugsymbols-11.0.21-linux-x64.tar.gz)

The complete command and its results are below:

pahole -J libjvm.debuginfo 
die__process_class: tag not supported 0x4106 (GNU_template_template_param) at <23490>!
Unsupported DW_TAG_reference_type(0x10): type: 0xba
