Thanks, but nothing stands out.

Well, the issue survived the reboot, hence it is stable, reproducible, 
and is definitely related to sip (but not in all settings, obviously). 

Checking the build logs uncovered a warning, I never noticed before:

gcc -c -pipe -march=i586 -mtune=i686  -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 
-fstack-protector  -funwind-tables -fasynchronous-unwind-tables -g -O2 -w -DNDEBUG -I. -o  parser.o parser.c
/home/phil/hg/sip/sip-4.12.1/sipgen/parser.c: In function 'yyparse':
/home/phil/hg/sip/sip-4.12.1/sipgen/parser.y:3070: note: 'sname' was  declared here

but since you supply the parser.c, any adverse effects would have bitten 
you, too.

My last resort are compiler options, but even imaging a compiler switch, 
that is able to change the code behavior in such fundamental ways sounds 
pretty unlikely. Given, that the rest of sip seems to do fine only adds 
to the fact of being pretty esoteric. Anyway, my gcc is 4.3.3.

I already send you the warnings that the automatic python code check
generated that you related to the unfixable python interface. When 
looking over the list, it seems to have grown some WARNINGs and 
(must fix!) attributions, that might be worth looking into again:

Other than that, I'm pretty baffled at the moment. How could I debug 
this issue any further? If I'm going to try bisecting it, would you 
think, that rebuilding sip is sufficient (supposed, that 4.12 will 
not be affected, and hence the issue won't cross library version 
changes)?

Begging-for-ideas-ly-yours,
