To my understanding the problem is that a sigjmp_buf is embedded into the main
perl interpreter structure.

cop.h:
struct jmpenv {                                                                 
    struct jmpenv *     je_prev;                                                
    Sigjmp_buf          je_buf;         <---- jmpbuf                            
    int                 je_ret;                                           
    bool                je_mustcatch;                                    
};
typedef struct jmpenv JMPENV;

intrpvar.h:
...
PERLVAR(I, top_env,     JMPENV *)                  
PERLVAR(I, start_env,   JMPENV)        <---- !!!            
PERLVARI(I, errors,     SV *,   NULL)
...

The struct interpreter is passed to many .so's involved with perl via my_perl
argument.  In one of the examples I've debugged the problem arose from having
perl-version built with the old glibc headers and perl itself with the new
version.

So the /usr/lib64/perl5/vendor_perl/auto/version/vxs/vxs.so module coming from
perl-version used different offsets into the my_perl structure than perl
itself.

If all the required perl .so files come from RPMs rebuilding all of them at
once should help. What I don't know is whether perl .so files dealing with
struct interpreter might come in from other sources as well like CPAN?!
