Free42 bug, or my mistake?

Free42 bug, or my mistake?
I'm playing around with Free42 at the moment, working the examples in the 42s manual, and notice that if I have a scalar value stored in variable MATA, MATB, or MATX, and then start the SIMQ (simultaneous equations) routine and input reasonable dimensions when requested, the program crashes. On 64-bit desktop Linux the crash is immediate, but on Android it hangs for about 10 seconds before crashing.

Has anybody else come across this? Is the real 42s affected? Should I report it as a bug?

Thanks.

RE: Free42 bug, or my mistake?
Do you mean the Thomas Okken "Free42 — An HP-42S Calculator Simulator"?
I never tried it, but it seems a nice project, it evens has binaries for Windows!

That said, I prefer to use emulators where the real ROM firmware from the original calculator is used. It will give a closer behavior to the real physical device.

There a few emulators for the HP-42S, I am using at the moment the Christoph Giesselink version for Windows.

In case You do not run Windows natively, you can use a hosted hypervisor for your preferred hosting operating system.

By the way, what is the 42S manual that you are referring to?
Maybe I can duplicate the issue in my emulator program here.

Can confirm the bug on Linux and iPhone.

I don't understand your problem, but why don't you contact Thomas Okken directly?

I have checked a few examples on solving simultaneous equations using matrices from this "HP42S Programming Examples and Techniques" guide, starting on page 163.

No issues when using the Christoph Giesselink's emulator as well.

This is a bug, and it affects all versions. It will be fixed in the next release.

Thomas, a bit of feedback - the update was delivered perfectly through Google Play to my Nexus 7 tablet running Android version 4.4.2.


Regards,

+1 (nice to know Google Play auto-update works for apps other than those that advertise too)

Release 1.5.3 of Free42 was also delivered automatically (presumably at the same time) to my Samsung Galaxy S4. Thanks Thomas K!!
