The SDCC linker segfaults in libc when trying to link any object files.
There's no segfault when using sdcc 3.6.0-3, or using sdcc compiled from upstream sources (svn-#9948)

Additional info:
sdcc 3.6.0-4

Steps to reproduce:

Try to compile a project that has any two *.c files and try to link them. For example

sdcc -c a.c
sdcc -c main.c
sdcc a.rel main.rel -o main.hex

Causes the follwing segfault in sdld:

sdld[12227]: segfault at ff7c820 ip 00007f1b1da0a8c6 sp 00007ffef70c00b8 error 4 in[7f1b1d988000+19d000]

This task depends upon

I also noticed this problem. I believe this is fixed by revision #9119:

The problem is that -std=c99 removes the definition of strdup, so GCC considers that it returns an int and proceeds to strip the topmost 32bits of its result, leading to a crash.

I have run into the same problem (sdld segfault)

AUR package sigrok-firmware-fx2lafw ( cannot build anymore.

Here is an observation:

With the previous sdcc package (sdcc-3.6.0-3-x86_64.pkg.tar.xz) the builds completes as it should...
But with the latest sdcc package (sdcc-3.6.0-4-x86_64.pkg.tar.xz) the build segfaults in sdld...

I'm trying to compile:

and I get Segmentation fault.

Downgrading to sdcc-3.6.0-3 also solves the problem.
