Error in Scanning binaries for linking errors

[ahzeeshan (Zeeshan Ahmad)]

On MacOS Catalina, I ran a sudo port selfupdate which gave the following:

--->  Updating MacPorts base sources using rsync
MacPorts base version 2.6.2 installed,
MacPorts base version 2.6.2 downloaded.
--->  Updating the ports tree
--->  MacPorts base is already the latest version

The ports tree has been updated. To upgrade your installed ports, you should run
  port upgrade outdated

After running sudo port upgrade outdated, I got the following error:

Nothing to upgrade.
--->  Scanning binaries for linking errors
      [                                        ]  81.4 %[5]    10054 killed     sudo port upgrade outdated

Can you reproduce the error (with e.g. sudo port -d rev-upgrade)? Was there a crash log generated?

[ahzeeshan (Zeeshan Ahmad)]

Cannot reproduce it today.

➜ ~ sudo port upgrade outdated Nothing to upgrade. ---> Scanning binaries for linking errors ---> No broken files found. ---> No broken ports found.

However, my matplotlib was still giving an error while importing (which was the reason I did a sudo port selfupdate in the first place),

import matplotlib.pyplot as plt

Traceback (most recent call last):

So I did a sudo port uninstall py37-pytorch (py37-matplotlib was installed as a dependency of py37-pytorch). When running sudo port install py37-pytorch, I got the error again:

A crash log would be in /Library/Logs/DiagnosticReports or ~/Library/Logs/DiagnosticReports.

[jmroot (Joshua Root)]

The error importing matplotlib was #60074 by the way.

[ahzeeshan (Zeeshan Ahmad)]

crash-log

[ahzeeshan (Zeeshan Ahmad)]

Just attached the crash log I found in /Library/Logs/DiagnosticReports/. Not sure how helpful it is.

[ryandesign (Ryan Carsten Schmidt)]

So now we know that the crash is in ​our machista library's parse_macho function but we don't know what file libmachista was analyzing when it crashed.
