Summary0007002: Hashcat segfault issue after package upgrade
DescriptionSystem: WSL2 on Windows 10 build 19042.746.

After performing a `sudo apt update` and `sudo apt full-upgrade` operation, hashcat now encounters a segmentation fault for every command tested so far (with the exception of `hashcat -h`). The list of upgrade events from the relevant dpkg session is included in the "Additional Information" section below, and an example output set is included below.

Whatever the error is, hashcat seems to encounter it early on. Additionally, according to the dpkg logs, hashcat itself was not upgraded immediately before the issue occurred, so the problem would seem to be in a dependency, rather than hashcat itself. Notably, `pocl-opencl-icd`, `libpocl2`, and `libpocl2-common` were among the upgraded packages.

```
┌──(kali㉿Laptop-02)-[~]
└─$ hashcat -b
hashcat (v6.1.1) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

zsh: segmentation fault hashcat -b

┌──(kali㉿Laptop-02)-[~]
└─$ hashcat -I 139 ⨯
hashcat (v6.1.1) starting...

zsh: segmentation fault hashcat -I

┌──(kali㉿Laptop-02)-[~]
└─$
```
(Note that the last command uses a capital letter i, not an L or number one. It should list available cracking devices.)
This issue was additionally tested with an actual cracking command, which produced the same results as `hashcat -I`, above.
Steps To ReproduceInstall Kali in WSL2, as normal.
Run `sudo apt update && sudo apt full-upgrade --autoremove` after approximately 1/19/2021.
Attempt to start hashcat.
Additional Informationdpkg upgrade events from the relevant session (from `grep "upgrade" /var/log/dpkg.log`):
