when building and then checking patchelf on openSUSE Leap 15.5, the rename-dynamic-symbols.sh test fails. The test builds a test library and executable called many-syms-main, then runs patchelf to rename symbols and then checks that many-syms-main still runs successfully.
On Leap the run fails with many messages like
./many-syms-main: Symbol `f1947' causes overflow in R_X86_64_PC32 relocation
and then terminates with a Segmentation fault. The interesting bit is that it however fails so even before patchelf touches it.
The binary is built and linked with option -pie which produces an executable which is supposedly position independent but does not actually contain code position independent code which requires compiler option -fPIE (of -fpie or -fPIC or -fpic). As a result the calls in the generated assembly do not go through the PLT.
This patch merely adresses that by adding the -fPIE option to the CFLAGS for the test.
Thank you!
Please do your best to include a regression test
so that the quality of future releases can be preserved.
