scudo has the following comment: https://github.com/llvm/llvm-project/blob/734026347cca85cf0e242ef5f04896f55e0ac113/compiler-rt/lib/scudo/standalone/combined.h#L683-L686
I've got a report that application using scudo starts very slowly on machines using the NVIDIA proprietary driver. As it happened, it seems to do lots of realloc calls in a loop what is invisible with other allocators but is very slow with scudo, it happens for ~30 seconds according to the user reports. The trace while this happens is like that:
```

It looks like the driver is calling realloc with bigger values in some loop (enlargening some buffer while reading the data?):
