OpenJDK 8 Segfault on Startup

[Attie Grande]

Hi All,

I apologise if this is the wrong list, if it is, please let me know.
After getting a "waiting approval" / "members-only list" response, I
had another look at the available lists, but still feel this is the
most suitable.

I've been trying to get OpenJDK 8 running on Linux on an ARM platform,
using the Yocto Sumo recipes from meta-java [1].

Unfortunately, the result is a java executable that cannot startup
without hitting a SIGSEGV. Even running "simple" things like `java` or
`java -help` result in a segmentation fault.

Investigating with GDB shows that the segfault is in libjvm.so, but
there are no symbols in this region of memory, and the stack has been
destroyed (I suspect as part of the VM's operation?)

I've spent some time following the execution through this "fog of
war", and library functions like malloc(), strlen(), etc... are called
fairly regularly.

I'm confident that I've cleared the call to Arguments::parse() in
Threads::create_vm() [2], but this is getting messy, and surely cannot
be the correct way to debug JVM.

One of the last strings I see through strlen() before the segfault is
"I2C/C2I adapters", which points directly at
AdapterBlob::AdapterBlob() [3]... I don't know if that will give a
hint of state / progress to anyone in the know.

I've attached an error report: hs_err_pid5803.log.

- How would I go about debugging OpenJDK to figure out what's going on here?
- I have a series of patches applies (see below), are there any
obvious missing or harmful patches?
- Has anyone been down this road before?

Thanks in advance,
Attie
