Bug ID: 24697
Summary: ld powerpc 2.31.1 crashes when linking a library
containing R_PPC_EMB_SDA21 relocation symbols
Product: binutils
Version: 2.31
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: daan at scherft dot nl
Target Milestone: ---
At our project we need to link a 3rd party elf file for the powerpc gnu linker
(ld 2.31.1). This elf file contains symbols that use the R_PPC_EMB_SDA21
relocation type. Now the linker gives error message 'relocation
R_PPC_EMB_SDA21 cannot be used when making a shared object' and then crashes
with a bus-error and message 'double free or corruption (out)'
Although I am not entire sure how to fix the R_PPC_EMB_SDA21 problem and if
that is actually a correct error message, for sure the linker should never
crash with 'double free or corruption (out)'.
Reproduce with:
usr/bin/powerpc-linux-gnu-gcc path/to/elf_file_with_R_PPC_EMB_SDA21.elf
Unfortunately I can't reproduce it without our 3rd party elf file, because I
don't know how to create a (test) library containing R_PPC_EMB_SDA21 relocation
symbols.
We use Debian Buster (on Intel), before on Debian Stretch with gcc 6.3.0 and
corresponding linker we didn't had that problem.
