Summary: MPPassManager::addLowerLevelRequiredPass may crash
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: release blocker
Priority: P
Component: new bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
the call 'FPP->add' in line 1635 (revision 137072 of
lib/VMCore/PassManager.cpp) may destroy the 'RequiredPass' if such a Pass is
already scheduled. This results in a dangling pointer of 'RequiredPass' which
is added to the LU container in line 1639. Finally this leads to a core dump.
