Please test with r55748. |
|
|
Benito ping... Does r55748 make any difference? |
|
|
It has only happened once so far even without the patch... |
|
|
This is either fixed or it was a temporary hiccup. Resolving. |

You should debug the code yourself. The first backtrace looks useful but sometimes only debugging reveals the actual location of error. I added an assertion in r56376 but it may not help. According to your BT no references are Nil. They can still be freed and invalid. Your latest backtrace is not very useful. It only has hex numbers. |

|
Today it crashed on Travis again... But not again my computer despite not updating and running the lazbuild version that crashed before. It is a very rare occurrence. |
