LYX crash - SIGFPE signal caught

Postby amirmit » Sat Jan 19, 2019 10:27 am


I'm using LYX 2.3 version on Win.
When I try to save my document, I get an error popup: "LYX crashed! SIGSPF signal caught! Bye".

What can I do to fix this?

Welcome to the forum!

SIGFPE refers to a floating-point exception, so an arithmetic error. No clue yet why it happens in the moment of saving though.

Do you use the latest version 2.3.2, or still 2.3.0 or 2.3.1? You could upgrade. Some bugs related to crashes have been fixed in 2.3.2.
