This is the second time that I crash the Julia client when using LinearAlgebra’ish code. I can not provide a minimal working example yet, but I am working on it. I want to ask here early, because maybe that kind of issue is known.

Windows 10

```julia
Julia Version 1.6.0
Commit f9720dc2eb (2021-03-24 12:55 UTC)
Platform Info:
  OS: Windows (x86_64-w64-mingw32)

  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-11.0.1 (ORCJIT, skylake)

I can run my code with a small memory footprint and then it crashes with a slightly larger memory need with the following error message:

```

```julia

```

I carefully checked that the memory requirements are way below my total RAM. I want to stress here that my code is working fine until a certain parameter range is met (size of sparse matrices/ dense vectors).

I suspect either a (weird) bug in the openBLAS implementation I use or Windows Defender. Any hints appreciated!

I checked the same code on

```julia
Julia Version 1.6.0
Commit f9720dc2eb (2021-03-24 12:55 UTC)
Platform Info:
  OS: Linux (x86_64-pc-linux-gnu)
  CPU: Intel(R) Core(TM) i3-8100 CPU @ 3.60GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-11.0.1 (ORCJIT, skylake)

```

And it works for all parameters.

Everything works on WSL on the same Windows machine. I will just use that and dont bother finding the bug right now.
