Re: [iPAQ] segmentation fault error on ipaq

A quick question:

There appears to be a bug in the GCC-ARM toolchain related to optimizations.
The skiffclusters seem to use different versions of GCC which exhibit this
behaviour differently.

For example, if you build something with optimizations on skiffcluster1, you
may encounter a very strange assembly-level error (it mentions something about
IMM8_OFFSET or something).

However, if you build on skiffcluster4 with optimizations, it will likely
build okay...however when you run it the program segfaults.

I've seen this behaviour with Squeak, others have seen it with SpeakFreely..it
is a GCC toolchain bug. My question: are you using optimizations? (ie -O3)
And secondly, which skiff machine are you building on? Try building without
any optimizations and see what happens.

...just my 0x02.
