Description
The issue was reproduced on Ubuntu Noble 24.04 armhf. 
A number of tier1 codegen/c1 tests hang randomly. 
I could not reproduce it in Jammy. 

The reproducer is 
'java -XX:+TieredCompilation  -version' in release or fastdebug configuration.
The process is locked up and does not produce crashdump.

This could be some followup remaining from JDK-8315940

Hi, The build is using gcc-13 which is default in Ubuntu 24.04. The issue is not specific to the gcc version, as we have the same problem in 25.04 (plucky)[1] Best Regards, Vladimir.

[~vpetko] should the build be compiled with default tools from Ubuntu 24.04? What GCC version was used?
