Summary: Module dtor segfaults on empty PHI nodes.
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Keywords: quality-of-implementation
Severity: normal
Priority: P2
Component: Core LLVM classes
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
CC: [email protected]
If a module has an empty PHI node (a PHI node on which addIncomingBlock() has
not been called), then it segfaults while the module object is destroyed. It
can be reproduced by the attached test program.
Probably can be fixed by modifying User::dropHungoffUses().
