Arrgh - I enabled the coredumps as you said, recompiled with "-g -O - 
fsigned-char" (the latter option is needed for PowerPC gcc) , and now it  
doesn't crash any more! IMHO, this might be an indication for a stack  
corruption or buffer overflow somewhere in the code... Not a very good  
situation, isn't it?

I added some more warning options to CFLAGS (then using "-g -O -fsigned- 
char -Wall -Wcast-align -Wshadow -Wstrict-prototypes -Wunused - 
Wuninitialized -pedantic -Wmissing-declarations -Wmissing-prototypes"),  
and got besides tons of non-critical stuff (?, pointers w/ different  
signedness) the following ones which *might* be fishy:

iso7816.c:106: warning: overflow in implicit constant conversion
app-openpgp.c:1186: warning: overflow in implicit constant conversion
app-nks.c:491: warning: overflow in implicit constant conversion
app-dinsig.c:403: warning: overflow in implicit constant conversion

Any ideas?

Cheers, Albrecht.
