Bug ID: 26615
Summary: powerpc: libc segfaults when LD_PRELOADed with libgcc
Product: glibc
Version: 2.28
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: rzinsly at linux dot ibm.com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
On RHEL 8.2 if you try to run:
$ LD_PRELOAD=/lib64/libgcc_s.so.1 /lib64/libc.so.6
You will get a segmentation fault on powerpc64le, this is due to an
_rtld_global_ro._dl_powerpc_cpu_features access without checking for a
_rtld_global_ro reallocation.
This patch fix the issue:
