The current FPC package builds fine in qemu for me. I will attempt

Qemu allows unaligned memory accesses, which do not always work on real
hardware, especially on armv5 and other older arms.
Is there a list anywhere of what hardware the buildds run on and/or
any other interesting information about their setups so I can try
to figure out what if anything the failing buildds have in common.
Has anything changed in ancina's configuration recently?
All currently running armel buildd's are identical marvell mv78x00
boards. Updates on ancina are the regular "apt-get upgrades" to get
latest toolchain
etc in sid.
There were issues with some versions of FPC, related to more than a
certain number of parameters (four?) being passed. Jonas wrote the

Do you know if that fix has made it into any stable releases and if so
which ones?

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).
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).

There might be alignment issues on ARM and SPARC but I've only seen
those with Lazarus, not with FPC itself.
