[Octave-bug-tracker] [bug #64735] `pkg load io` crashes Octave GUI with no error

[Arun Giridhar]

Follow-up Comment #11, bug #64735 (project octave):

The minor difference from bug #60620 is that there the JVM loaded without a
problem but any subsequent operation like a matrix multiplication caused a
crash. Here loading the JVM itself causes the crash.

Reading the strace output, this is what I think is happening:

* Loading the io package calls javachk, which is known to reduce the stack
size.

* Loading Java on OP's machine calls up the Sentinel security module, which is
now operating with an unexpectedly small stack.

* Stack overflow within the Java modules --> crash.
