Hello,
Using standard compiler from HP with version as shown below
C-ANSI-C C.06.25 HP C/aC++ Compiler
We get an the following during make .
"DBI.xs", line 3007: warning #2546-D: transfer of control bypasses
initialization of:
variable "h_perl" (declared at line 3078)
goto is_DESTROY_wrong_thread;
^
To me it looks like this
PerlInterpreter * h_perl = DBIc_THR_USER(imp_xxh) ;
if (h_perl != my_perl) {
/* XXX could call a 'handle clone' method here?, for dbh's at least */
if (is_DESTROY) {
is_DESTROY_wrong_thread:
if (trace_level >= 3) {
PerlIO_printf(DBILOGFP," DESTROY ignored because DBI %sh handle (%s) is owned by thread %p not current thread %p\n",
dbih_htype_name(DBIc_TYPE(imp_xxh)), HvNAME(DBIc_IMP_STASH(imp_xxh)),
(void*)DBIc_THR_USER(imp_xxh), (void*)my_perl) ;
PerlIO_flush(DBILOGFP);
}
XSRETURN(0); /* don't DESTROY handle, if it is not our's !*/
}
Not 100% on the error but is it use of a uninitialized h_perl in the PerlIO_printf statement. If trace level is greater than 3?
Regards,
Esmond
