This is a bug report for perl from efifer@sanwaint.com\, generated with the help of perlbug 1.27 running under perl v5.5.650.
This is a simple example of an embedded perl interpreter:
#include \<EXTERN.h> #include \<perl.h> #include "XSUB.h"
static PerlInterpreter *my_perl;
int main(int argc\, char **argv\, char **env) { SV *sv;
my_perl = perl_alloc(); perl_construct(my_perl); perl_parse(my_perl\, NULL\, argc\, argv\, (char **)NULL); perl_run(my_perl);
perl_call_pv("xxx"\, G_DISCARD);
perl_destruct(my_perl); perl_free(my_perl); }
Sometime since perl5.005_03 "inhibit_exit" in the debugger stopped working. With perl5.005_03 using this xxx.pl script\,
print "hello\n";
sub xxx { print "xxx\n"; }
I have a debugging session like:
% ./interp -I../perl5.005_03/lib -d xxx.pl
Loading DB routines from perl5db.pl version 1.0402 Emacs support available.
Enter h or `h h' for help.
main::(xxx.pl:1): print "hello\n";
DB\<1> b xxx
DB\<2> c
hello
Debugged program terminated. Use q to quit or R to restart\,
use O inhibit_exit to avoid stopping after program termination\,
h q\, h R or h O to get additional info.
DB\<2> O inhibit_exit
inhibit_exit = '1'
DB\<3> q
main::xxx(xxx.pl:4): print "xxx\n";
DB\<3> $DB::finished = 0
DB\<4> c xxx
However\, with perl5.5.650 the call to perl_run exits without ever returning (so perl_call_pv never occurs):
% ./interp -I../perl5.5.650/lib -d xxx.pl
Loading DB routines from perl5db.pl version 1.05 Emacs support available.
Enter h or `h h' for help\, run `perldoc perldebug' for more help.
main::(xxx.pl:1): print "hello\n";
DB\<1> b xxx
DB\<2> c
hello
Debugged program terminated. Use q to quit or R to restart\,
use O inhibit_exit to avoid stopping after program termination\,
h q\, h R or h O to get additional info.
DB\<2> O inhibit_exit
inhibit_exit = '1'
DB\<3> q
Am I doing something wrong or is something broken?
Thanks.
