PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
Stack dump:
0. Program arguments: llvm-bolt /home/gomezjc/tmp/postgres-binaries/postgres-17-5-pgo-intel-bolt-flags -update-debug\
-sections -o csdd-17-5-pgo-bolt-lp1-pid-800-db -data=""

Not the crash above only happens when I see the -update-debug\
-sections , if I do not use that flag the optimized binary gets created and works properly, however for debugability we need to preserve debug sections for this binary.
