[LLVMdev] Stack overflow in Legalize Op
This isn't running in a child process, but this is a win32 machine.
The problem I'm having is LegalizeOp is recursively calling itself 6
times, followed by 3 calls to ExpandEXTRACT_VECTOR_ELT, with each
LegalizeOp pushing 20KBof data onto the stack and Expand pushing 800B of
data on the stack. So that is 9 function calls pushing ~140KB of data
onto the stack. This set of 9 function calls repeats itself 25 times,
pushing almost 3.5 MB of data onto the stack.
This is occurring with v1...

Are you running with restricted stack size, e.g. in a pthread process?

[LLVMdev] Stack overflow in Legalize Op
I'm hitting an issue where legalizeOp is overflowing the stack. Are
there any recommended ways of getting around this?
The bitcode that causes this issue is attached.
