I have just switched from 64-bit gentoo to 32-bit and almost everything I need is working. Except Frozen-bubble. I get no errors installing it, but when I run it, all I get is

[SDL Init] segmentation fault.

Is there a way to get a bit more information?

The SDL components and their revisions are the same for both 64- and 32-bit, with the exception of sdl-image 1.2.6-r1 vs 1.2.7, and emul-linux-x86-sdl which is only needed on the 64-bit system.

My searches have turned up a few bits, but they are several years old.

Where do I look?

TIA

Try to start it with strace, like this
strace <command>
It will throw a lot of text at you, but you can try to find the place where it broke.
Usually, segfaults are the most difficult problems to troubleshoot.

Thanks. It gave me a bit over 2000 lines to sort through. Tomorrow I will repeat with the version that works and compare the two.

No, strictly speaking you need just some couple dozen of lines just before the "Segmentation fault" message. The might indicate what went wrong.
