I don't seem to get the same answers from addr2line and gdb 4.17 on 1.4/i386.
Am I missing something?

In brief:

(gdb) file rfb.cgi
(gdb) core rfb.cgi.core
Program terminated with signal 11, Segmentation fault.
(gdb) bt
#0  0x40117370 in free ()

#2  0x400b23be in PQclear (res=0x68000) at fe-exec.c:311


% addr2line -e rfb.cgi 0x40117370
