1735	Pmc2c line numbering confuses gdb	plobsing	dukeleto	"Using the default configuration, gdb is unable to step through vtables, giving messages such as:

{{{

0x00007ffff7a90ae4 in Parrot_OpLib_init_pmc (
    interp=0x60a080, _self=0x789770, 
    name_pmc=0x7892d0)
   from /home/pitr/dev/parrot/dynop_mapping/blib/lib/libparrot.so.2.6.0
(gdb) n
Single stepping until exit from function Parrot_OpLib_init_pmc, 
which has no line number information.

    init=0x7892d0) at src/pmc.c:551

}}}

This is a significant drag because much Parrot functionality is inside vtables.

Reconfiguring with --no-line-directives, which disables line directive generation from tools such as pmc2c, the vtables become steppable."	bug	new	normal		tools	2.6.0	medium
