Hello,
When I use -ipa, -OPT:alias=field_sensitive (open64 v5.0)
The compiler breaks at IPA_LINK with a signal 11 error
It appears that the function Get_siloed_references() is called
within IPA_irb_write_nystrom_alias_info (in ipa_be_write.cxx), even though
I am NOT turning on siloed analysis.
Here's the gdb trace:
