3DS: Attempting to apply GUI themes besides the default one causes a stack overflow

Description

Port: 3DS
Hardware: New Nintendo 3DS (North American Black Friday 2016 Edition [not XL])

Last version without bug: 2.1.0
First version with bug: 2.1.1
Commit in which bug was introduced: f22e078

Steps to Reproduce Bug:
1) Open ScummVM
2) Press 'Options...' button.
3) Scroll to and select 'Misc' tab.
4) Press 'Theme:' button.
5) Select 'ScummVM Modern Theme' or 'ScummVM Modern Theme Remastered' ('ScummVM Classic Theme is the same as the default theme).
6) Press 'Choose' button.
7) Press 'Apply' or 'OK' button. System crashes and the Luma crash screen appears. The stack dump that displays in the bottom screen is empty, indicating a stack overflow.

The file sizes for each of the ScummVM themes (as of b4fd25a) is as follows:

  • scummclassic.zip: 160.4 kB
  • scummmodern.zip: 290.5 kB
  • scummremastered.zip: 288.5 kB

The 3DS's memory stack is 256kB, so the classic theme is the only one that works. 3DS releases of ScummVM prior to 2.1.1 applied themes differently, most notably requiring support files to be located separately on the SD card rather than be embedded within the ScummVM application itself.

Hi,

Switching themes works fine for me. Incidentally, the commit you reference was mostly motivated by the need to have themes working without having to copy files to the SD card.

Does the issue occur with the release build from the ScummVM downloads page or with the builds from buildbot?
If it happens only with your own builds, you might want to check the version of FreeType you are using. We require an old version, as newer versions allocate too much on the stack. I use version 2.6.5.

Just tried the latest dev build from buildbot, it works fine. I had my freetype installed through dkp-pacman, and sure enough it builds from 2.9. Can I ask what you did to install 2.6.5?

EDIT: Nevermind, I think I got it.

EDIT 2: Yep, that was definitely the problem.
