1) The exact version of GCC:

$ gcc --version
gcc (Ubuntu 8.2.0-7ubuntu1) 8.2.0

2) The system type:

x86_64-linux-gnu.
On Ubuntu 18.10.

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

/usr/bin/cc -DCOLORIZE_CONSOLE -DSINGLE_BINARY -DUSE_SELECT -DVECTORIZE_SINCOS
-DXASH_BUILD_COMMIT=\"b5b493b1\" -DXASH_DEDICATED -DXASH_FASTSTR
-DXASH_FORCEINLINE -DXASH_USE_STB_SPRINTF

-I/home/a1ba/projects/xash/xash3d/engine/../common
-I/home/a1ba/projects/xash/xash3d/engine/../pm_shared  -m32 -save-temps -g -O2
-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.
