fedor.sergeev added a comment.

Just FYI for now as I'm trying to dig futher...
I have been trying this fix in our downstream environment and managed to get a hang with this backtrace:

#0 needPadding (BoundarySize=<optimized out>, Size=<optimized out>, StartAddr=<optimized out>) at ./llvm/lib/MC/MCAssembler.cpp:1028
#1 llvm::MCAssembler::relaxMachineDependent (this=<optimized out>, Layout=..., MF=...) at ./llvm/lib/MC/MCAssembler.cpp:1077
#2 0x00007ffff1adc8b6 in llvm::MCAssembler::layoutSectionOnce (this=this at entry=0x7fff90580580, Layout=..., Sec=...) at ./orca/llvm/lib/MC/MCAssembler.cpp:1213
...

Working on getting upstream reproducer....
