iOS built from the source code of 3.2.4 beta6 load texture failed when compress mode set to lossy

[alexzheng]

Godot version:

3.2.4 beta6 source code

OS/device including version:

Issue description:

Steps to reproduce:

1. set the compress mode to Lossy when import a jpg image , keep default for other settings
   2.Export an Xcode project in 3.2.4 beta6, it can run
   3.build a library (.a) from the source code from https://downloads.tuxfamily.org/godotengine/3.2.4/beta6/godot-3.2.4-beta6.tar.xz
   4.replace the library file with the custom one
   5.run the project, it crashed:

when change the compress mode to Lossless for the image, it can run with that custom library file.

@alexzheng Does it work if you use the official iOS export template?

[alexzheng]

It works use the official iOS export template.
However, it crashed when I replace the .a file with my build lib file. I did not change any code in the source code and my build lib file can works in any project if the compress mode is not set to Lossy.

[alexzheng]

And my custom lib built from 3.2.3 source code, can run fine for that project, which import texture using compress mode set to Lossy.

[clayjohn]

Can you provide more information about your custom library? It is clear that it is causing the issue somehow.

[alexzheng]

After a clean build, it works now.
