[Bug c/35193] New: can't find a register in class 'R1_REGS' while reloading 'asm'

["b dot gunreben at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

when I try to compile a current glibc for hppa, I get the following error:
gcc -O2 -c dcigettext.i
dcigettext.c: In function ‘_nl_find_msg’:
../ports/sysdeps/unix/sysv/linux/hppa/nptl/lowlevellock.h:220: error: can't
find a register in class 'R1_REGS' while reloading 'asm'
dcigettext.c:1102: error: can't find a register in class 'R1_REGS' while
reloading 'asm'
dcigettext.c:1164: error: can't find a register in class 'R1_REGS' while
reloading 'asm'
dcigettext.c:1194: error: can't find a register in class 'R1_REGS' while
reloading 'asm'
../ports/sysdeps/unix/sysv/linux/hppa/nptl/lowlevellock.h:220: error: 'asm'
operand has impossible constraints
dcigettext.c:1102: error: 'asm' operand has impossible constraints
dcigettext.c:1164: error: 'asm' operand has impossible constraints
dcigettext.c:1194: error: 'asm' operand has impossible constraints

however, if I remove the lines with starting # signs in the preprocessed code
like:

grep -v "^#" dcigettext.i > x.i

it just compiles. The original error also vanishes if I use -O instead of -O2.
Adding preprocessed dcigettext.i, to reproduce, run 

gcc -O2 -c dcigettext.i
