Also happens on Arch Linux with GCC 8.2.1.
3) the options given when GCC was configured/built;
See attachment.
4) the complete command line that triggers the bug

-fvisibility=hidden -o CMakeFiles/xash.dir/server/sv_init.c.o -c
/home/a1ba/projects/xash/xash3d/engine/server/sv_init.c
or in case of just sv_init.i
gcc -m32 -save-temps -g -O2 -fvisibility=hidden -o sv_init.o sv_init.i
5) the compiler output (error messages, warnings, etc.)
sv_init.s: Assembler messages:
sv_init.s:31551: Error: can't resolve `L0' {*ABS* section} - `.LC28'
{.rodata.str1.1 section}
6) the preprocessed file (*.i*) that triggers the bug, generated by adding
-save-temps to the complete compilation command
See attachment.
I tried to compile without -O2, -g or -m32 and it seems only this combination
makes assembler to fail.
