Bug #: 13483
Summary: gdb not taking 0 for pointer and boolean values
Product: gdb
Version: unknown
Status: NEW
Severity: normal
Priority: P2
Component: gdb
AssignedTo: unassigned@sourceware.org
ReportedBy: dnovillo@google.com
Classification: Unclassified
I'm debugging cc1plus from GCC trunk (as of 2-3 weeks ago). I'm trying to make
an inferior call to the function libcpp/line-map.c:linemap_dump:
1160 void
1161 linemap_dump (FILE *stream, struct line_maps *set, unsigned ix, bool
is_macro)
(gdb) call linemap_dump(0,line_table,ix,0)
Cannot resolve function linemap_dump to any overloaded instance
But if I use typecasts, it works:
(gdb) call linemap_dump((FILE *)0,line_table,ix,(bool)0)
Map #0 [0x7ffff7fc2000] - LOC: 2 - REASON: LC_ENTER - SYSP: no
File: /usr/include/bits/posix1_lim.h:1
Included from: [-1] None
I suppose this is intended behaviour, but it is rather irritating. There is
exactly one linemap_dump function, and I would expect 0 to be trivially
convertible to those types:
(gdb) l linemap_dum<TAB>
linemap_dump(_IO_FILE*, line_maps*, unsigned int, bool)
linemap_dump_location(line_maps*, unsigned int, _IO_FILE*)
Thanks. Diego.

Sorry, forgot to include that. We are using a slightly modified version of 7.3.1: $ gdb --version GNU gdb (GDB) 7.3.1 If I cast the bool argument, it works fine, yes.
