Re: Frescobaldi Log Error -1073741819 on Windows10

[Aaron Hill]

Folks,

An Access Violation has nothing to do with permissions as was stated 
earlier.  This error code is specific to virtual memory management.  
Most often, this points to an error in programming logic such as a NULL 
pointer access but it could be any attempt to read from and or write to 
a virtual memory address that is invalid for the running process.

Based on threads earlier in the year, it would seem the Windows build of 
LilyPond is known to have some gnarly and difficult to source issues 
with memory management.  While it can often run without error, certain 
constructs in input will result in an AV.  In fact, it is one of the 
reasons why I stopped using the Windows build in favor of running the 
Linux version through the Windows Subsystem for Linux (WSL).  Also, it 
would seem there are very few and/or constrained resources for debugging 
this sort of thing, as the principal developers for LilyPond would seem 
to be mostly Linux-based.

Setting aside all that for a moment, Peter mentioned possible issues 
manifesting in other software, and also that the input file in question 
has worked before.  So the underlying issue most likely is caused by a 
recent change to the system.  The fact that closing other running apps 
helped once would make me think that there is an issue with excessive 
memory consumption.  Programs that do not handle out-of-memory 
conditions well can often run afoul of an AV.

@Peter: Would you kindly verify a few things?

- Does LilyPond work at all?  That is, are you only noticing issues with 
particular input files or does it fail the same way even for simple 
inputs?  Also, is this issue occurring when building through 
Frescobaldi, or does it also occur if you just launch LilyPond manually?

- Can you reproduce these issues when running LilyPond after a clean 
reboot of the machine while running as little else as possible?

- Since this issue seems to impact two devices, have you installed 
anything recently on both machines?  Also, have you made any 
configuration changes that would have applied to both devices?
