Subject: [Bug tree-optimization/104038] New: ranger infinite loop on a PHI statement
Date: Fri, 14 Jan 2022 21:58:07 +0000 [thread overview]
Message-ID: <bug-104038-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104038
Bug ID: 104038
Summary: ranger infinite loop on a PHI statement
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
I'm debugging what looks like an infinite loop deep in Ranger. Interrupting
with SIGABRT the cc1plus process while under GDB produces the backtrace below.
Returning eventually re-enters the infinite loop in
gimple_ranger::prefill_stmt_dependencies().
The statement being processed at the highest level is:
_11 = PHI <_2493(5), _27180(6)>
Program received signal SIGABRT, Aborted.
