Solved SDCC package seems broken

Hello i am trying to get SDCC compiler working but it seems that binary packet is broken, i install the package with:
pkg install sdcc
But whenIi execute it some times breaks and another shows help, but the 90% of tries it crashes with a core dumped file.
Code:
Garrus # ~> sdcc
Segmentation fault (core dumped)
When it works, it show the help message:
Code:
Garrus # ~> sdcc

Is there any way to debug it to know if its something related to my pc?
Should I try ports version or source code version in SDCC http://sdcc.sourceforge.net/index.php#Download ?
 
You might want to ask the maintainer if they can update the port. I see a 4.2.0 on the website, the port is still at 4.0.0.
 
I have wrote to port mantainer to update, meanwhile i have compiled source code in a test machine and it behaves the same thing, it crashes almost all execution times, thats my compiled version:
test # ~/sdcc> ./bin/sdcc
SDCC : z80/z180/ez80_z80/z80n 4.2.2 #13470 (FreeBSD)
Maybe FreeBSD doesnt work well with that software, the offical supported OS are:
Linux - x86, Microsoft Windows - x86, Microsoft Windows - x86_64 and Mac OS X are the primary, so called "officially supported" platforms.
I have tested under Linuxulator and it works, but i prefer a native compiler without "tricks".
Any idea?

I see absolutely no reason why this specific software couldn't run on FreeBSD. The list of ' officially' supported OSs usually doesn't include FreeBSD, that doesn't mean it's impossible run on FreeBSD.

I'll see if I can test some things. I've got a ton of compilers/assemblers for other 8 bit CPUs already, the Z80 was actually missing from that collection ;)
 
I am using the same FreeBSD version, maybe some security option is denying some access, i will try using truss.

I think that the key is:
Code:
setrlimit(RLIMIT_STACK,{ cur=4194304,max=4194304 }) = 0 (0x0)
SIGNAL 11 (SIGSEGV) code=SEGV_ACCERR trapno=12 addr=0x7fffff8c2238

I will investigate about setrlimit syscall
 
I now have it installed on a 13.0-RELEASE machine. Ran sdcc several times in a row, not once did it crash. The biggest difference I see is that I built lang/sdcc on my own package repository. I need to try the package from the official repository.

_Darius_ Is it possible the source picks up on CPU features during the build? The official packages are built on relatively new hardware, that might enable certain CPU features. If you run that code on a CPU that doesn't have these features it's going to crash. I'm thinking AVX, SSE, etc. might be possible issue.

kr0m can you try building lang/sdcc from ports? If there are issues with CPU features, building it on your own system should eliminate this potential incompatibility.
 
I will try to build, but i am not very confident with FreeBSD systems, i am using binary packages for all the installed software in the system, if i mix some packages from binary and others from ports will i get in troubles?
When a port asks to compile some library dependencies, that dependency port will sustitute my binary installed library?
In that case the binary sofware can be confused about installed libraries and expected ones?
 
Sorry _Darius_ i didnt readed you, you are right the problem is related with ASLR, i have set:
elfctl -e +noaslrstkgap /usr/local/bin/sdcc

And it works 100% of times, thank you very much.

Not if we're careful. In this specific case we can guide you through the process.

So much for my theory. No need to build the port in that case ;)

If you don't mind me asking, where are you going to use sdcc for? I'm familiar with the old 8051, did some assembler on it a long time ago. I've also done 6502/6510, 6809 and 680x0 assembler. Recently revived my old school 8 bit knowledge and built my own 6502 based SBC. The Z80 is on my list of CPUs to play with next. Didn't know sdcc, so thanks for bringing it to my attention.

Great, I am not sure exactly what version has the ASLR stack gap fixed but this should be a useful stop gap for now.

I am coding a GameBoy game, only for learning something new :)


As SDCC compiler works as expected after disabling ASLR for the binary, i close the thread as resolved, thank you guys for the assistance and help.
