libgc1-8.2.0-1.4 RPM for ppc64le

From OpenSuSE Ports Tumbleweed for ppc64le

Name: libgc1 Distribution: openSUSE Tumbleweed
Version: 8.2.0 Vendor: openSUSE
Release: 1.4 Build date: Wed Jun 15 04:31:00 2022
Group: System/Libraries Build host: obs-power9-11
Size: 467424 Source RPM: gc-8.2.0-1.4.src.rpm
Summary: A garbage collector for C and C++
The Boehm-Demers-Weiser conservative garbage collector can be used as a
garbage collecting replacement for C malloc or C++ new. It allows you
to allocate memory basically as you normally would, without explicitly
deallocating memory that is no longer useful. The collector
automatically recycles memory when it determines that it can no longer
be otherwise accessed.
