Hi Nithesh,

Thanks a lot for reporting the bug!

From the info I can see that your application is 32 bit, and, that, most likely, your kernel is newer than 2.6.27. The problem has been overlooked mostly because 90% of maze users run 64 bit applications, that no longer use the "sysenter" machine instruction.

Please post the output of these two shell commands:

uname -a

cat /etc/*-release

Having this information about you system will enable us to to fix the bug.

Cheers,

Roni.

Thank you, Nithesh.

Could you also tell me if the OS is 32 bit, and if the Red Hat Enterprise release is 5 or 5.<something>? The two shell commands above would have given you the complete info...

Re: core dump 6 years ago #5

its 32 bit machine
Red Hat Enterprise Linux Server release 5 (Tikanga)

Thanks! We will build the system and try to reproduce the problem. This may take several days. I'll keep you posted.

I built your system equivalent, reproduced the bug, and fixed it.

Previously 32 bit maze has been tested only on x86_64 machines. On those the 32 bit system calls used "sysenter" instruction. On i686 it was "int $0x80" though. That was why the assertion failed: it did not recognize the correct instruction code in your process' address space.

However I found several problems which you may encounter when running maze on i686 machine. Please bear with me for another few days. I will fix the issues and then update the 32 bit maze.
