utils/TableGen/CodeGenDAGPatterns.cpp
Product: libraries
Version: trunk
Hardware: PC

Screen capture.
I apologize for submitting this report without trying to find the problem
myself. I'm only recently reacquainted with C++ and don't have enough knowledge
of the internals.
This looks like a problem in berase_if() in DAGISelEmitter.cpp. I have attached
the first half of the stack trace.
I am running Visual Studio 2019 on Windows 7.
This problem occurs when building the PowerPC and X86 targets. It does not
occur when building AMDGPU, ARM, NVPTX, or SystemZ.
The problem has been around for about a week. I ran this build under master,
which I rebased earlier today.
