Ticket #1735 (new bug)
Pmc2c line numbering confuses gdb
|Reported by:||plobsing||Owned by:||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. Parrot_pmc_new_init (interp=0x60a080, base_type=37, init=0x7892d0) at src/pmc.c:551 551 return pmc;
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.
