Crash of aliceVision_incrementalSfM.exe (due to reparse point/junction)

[butscher]

Describe the bug aliceVision_incrementalSfM.exe crashes when started by Meshroom

To Reproduce Tested with the dataset_monstree (all three variants) from https://github.com/alicevision/dataset_monstree

1. Import all images of the variant
2. Run the default pipeline for photogrammetry with default settings until or after "StructureFromMotion" node. It doesn't matter if the project is saved to a file beforehand or not.
3. With the start of "StructureFromMotion" a message from Windows appears that "aliceVision_incrementalSfM.exe" crashed and Meshroom shows a red bar to indicate an error.

Expected behavior No crash

Log

Windows 7 crash info (unfortunately in German). I think the important information is that the crash happened in module "ucrtbase.DLL" with exception code 40000015

Probably the same issue as https://github.com/alicevision/meshroom/issues/1088

[butscher]

You may know this better but I don't see a connection between a crash in FeatureExtraction step and one in StructureFromMotion step.

[natowi]

The connection is the crash in module "ucrtbase.DLL"

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[natowi]

Does the error persist with the latest release?

[butscher]

2021.1.0 fails in nearly exactly the same way except that the numbers in the additional information ("Zusatzinformation") 1 to 4 are different.

This issue is closed due to inactivity. Feel free to re-open if new information is available.

I found the reason for the crash:

I had created a junction (aka reparse point) at my "C:\Users\Butscher\AppData\Local\Temp" to a path on another volume. It seems that "aliceVision_incrementalSfM.exe" just can't handle that. When I replaced the "Temp" junction with a usual folder everything worked fine.

I will now try to workaround this problem by setting environment variables because I actually don't have enough space on C: for all temporary data.

It would be nice to have a setting in Meshroom to specify the temp directory.

[fabiencastan]

When you save your scene, the cache is relative to your ".mg" file. Temp is only used when the scene is not saved and there is a warning when you start the computation.

[butscher]

Thank you.

For some quick tests it is useful just to save to temp. I also tried previously to work with an explicitly created .mg file but unfortunately its location also had a junction in its path (I like junctions).
