Shared library
I noticed the following strip bug for the attached shared library:
❯ strip --version
GNU strip (GNU Binutils; openSUSE Tumbleweed) 2.43.1.20241209-7
❯ cp x.so y.so && strip -R .comment y.so && readelf -sW y.so 2>&1 | grep
gpm_data
59: 0000000000007a88 8 OBJECT GLOBAL DEFAULT BAD[0x17] gpm_data
❯ readelf -SW y.so
There are 23 section headers, starting at offset 0x5b28:
...
As seen, the section index for gpm_data points to an invalid section index.
llvm-strip works fine:
❯ cp x.so y.so && llvm-strip -R .comment y.so && readelf -sW y.so 2>&1 | grep
gpm_data
59: 0000000000007a88 8 OBJECT GLOBAL DEFAULT 23 gpm_data
