However, disassembling a .flt isn't terribly hard so I'll make sure after the change is in.

Verified.

FWIW, if you ever need to quickly disassemble a .flt,

Code: [Select]

arm-elf-objdump.exe  -m arm -Mforce-thumb -b binary -D lua.flt > lua.dis

The -Mforce-thumb took me a while to find the first time I wanted to do this. Obviously you don't get any symbols etc so the .elf is preferred when available.

Don't forget what the H stands for.

Changeset [2762]: add -fno-schedule-insns2 to fix intermittent lua errors, gcc bug ...
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38644

This makes really interesting reading for those following this thread. The underlying bug was first reported way back in 2008 and then never really dealt with. One can only speculate on how many ARM projects built using GCC were abandoned for random unreliability during interim period.

Wow, it sounds like you may have figured it out! I've been busy with family stuff (graduations, weddings etc) for awhile, but I'll try out the latest trunk with my time lapse patches as soon as I can. That was a tough one, but it makes it even sweeter when you solve it. Good job.

And thanks to you too for doing all the testing, and running the debug builds from reyalp that finally led to it being tracked down
