[Pkg-sugar-devel] Bug#862576: Bug#862576: etoys: Doesn't get beyond Squeak security key generation

[James Cameron]

@Petter, thanks for asking.

@Bert, etoys 5.0.2408 does not complete "Initializing Squeak security
system" on Debian Stretch, but it did on Debian Jessie.

I don't know what's wrong, yet.

I've reproduced the problem.

CPU is 100%.  strace shows the process making syscalls, of which the
most frequent are gettimeofday and recvfrom on socket, with occasional
SIGARLM.  http://dev.laptop.org/~quozl/z/1dHfBq.txt

The process has one thread with a backtrace;

(gdb) thread apply all bt

Thread 1 (Thread 0x7f46b3f3c500 (LWP 954)):

#2  0x000055f777013f77 in interpret ()
#3  0x000055f776ff9d39 in main ()

Repeated continue, ctrl+c and backtrace shows the squeak-vm is
actually doing something, but I've no idea what;

generate-core-file can be used, and the resulting core file can be
reloaded in gdb.  http://dev.laptop.org/~quozl/z/1dHfAf.txt

Perhaps one of the libraries changed between Jessie and Stretch to
cause this problem; but finding which one will be a long task.

Perhaps etoys upstream may have some ideas.  I've copied Bert.
