When running 2.4.0 on an ARM system (Debian v5 "Lenny", armel) with
limited memory (32Mb RAM + 768Mb swap) and using it to compile a large
project (Lazarus 0.9.28.2) I'm seeing intermittent failures which go
away if the make is restarted. I've not seen this running on other
platforms, and I don't believe it is a problem in the Lazarus sources
since the build will eventually complete giving me runnable code.
A couple of days ago I fixed an error in svn trunk for ARMEL that caused
the stack to become temporarily unbalanced after performing syscalls
with 5 or more parameters (the bug is still there for OABI, but I can't
fix that because I don't have access to an OABI machine).
I don't at the moment have any spare ARM systems that I could set up and
expose for testing. I've got some development boards (effectively,
ARM-based PCs) but they came with CE and I'm not paying the manufacturer
$500 for Linux...
A side-effect of that bug was that if the caller passed the address of
its own result as one of the parameters to the system call, it would
afterwards return a random value as its result and checks for error
results caused random failures like the one you posted (the reproducible
case that allowed me to fix it was a similar error).
That sounds promising and I'll try it in a few days (once I've got the
trial Lazarus compilations out of the way). What should I be doing-
updating to trunk?
The overall exercise is extending the native testing I did of FPC on
various platforms to Lazarus. Granted that not many people are likely to
want to run it natively on an ARM target but I think it's still worth
knowing whether it can be done.
