New issue 425: parse_file crashes with segfault in Fava (MacOS) https://bitbucket.org/blais/beancount/issues/425/parse_file-crashes-with-segfault-in-fava
Andrii Mostovyi: After editing ledger file in Fava editor, on file save fava crashes occasionally \(say, once-twice per day of heavy use\). After restart it works correctly. This problem is happening for a year\+ under different versions of fava and beancount \(current fava version is 1.14\). It crashes in `build_grammar_error_from_exception`\[1\] , but I am having a hard time figuring out where exactly. Maybe it’s worth asserting `PyErr_Occurred` as the first line in the method? Also, I would appreciate any tips on debugging this further. \[1\][https://bitbucket.org/blais/beancount/src/f6d6f008453514bbbcd4ad795ffd941e6365b7b3/beancount/parser/grammar.y?at=default#lines-40](https://bitbucket.org/blais/beancount/src/f6d6f008453514bbbcd4ad795ffd941e6365b7b3/beancount/parser/grammar.y?at=default#lines-40) Crash report \(removed non-relevant parts\): ``` Process: Python [1223] Path: /usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python Identifier: Python Version: 3.7.7 (3.7.7) Code Type: X86-64 (Native) Parent Process: ???
