Summary: std.c.stdarg problems with 8 or more integer arguments on x86_64 Product: D Version: D1 & D2 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: druntime AssignedTo: nob...@puremagic.com ReportedBy: grahamc00...@yahoo.co.uk --- Comment #0 from Graham <grahamc00...@yahoo.co.uk> 2011-10-02 04:10:43 PDT --- When there are 8 or more integer (not float or double) arguments to a vararg function as well as string arguments va_arg() appears to get some wrong argument details. This problem is present on both the D1 and D2 compilers. Code works fine with 32 bit compilation. Only a problem with 64 bit compilation. Example code attached. This might also seg fault in some circumstances. This displays (see incorrect information for arguments 9 and 10 in the first section): 9 variable arguments argument types [int, int, int, int, int, int, int, immutable(char)[], immutable(char)[]] 2) int arg = 2 3) int arg = 3 4) int arg = 4 5) int arg = 5 6) int arg = 6 7) int arg = 7 8) int arg = 8 9) string arg = '', length 0 10) string arg = '?', length 4764008 9 variable arguments argument types [double, int, int, int, int, int, int, immutable(char)[], immutable(char)[]] 2) double arg = 2.000000 3) int arg = 3 4) int arg = 4 5) int arg = 5 6) int arg = 6 7) int arg = 7 8) int arg = 8 9) string arg = '9', length 1 10) string arg = '10', length 2 9 variable arguments argument types [int, int, int, int, int, int, immutable(char)[], immutable(char)[], immutable(char)[]] 2) int arg = 2 3) int arg = 3 4) int arg = 4 5) int arg = 5 6) int arg = 6 7) int arg = 7 8) string arg = '8', length 1 9) string arg = '9', length 1 10) string arg = '10', length 2 9 variable arguments argument types [immutable(char)[], int, int, int, int, int, int, immutable(char)[], immutable(char)[]] 2) string arg = '2', length 1 3) int arg = 3 4) int arg = 4 5) int arg = 5 6) int arg = 6 7) int arg = 7 8) int arg = 8 9) string arg = '9', length 1 10) string arg = '10', length 2 -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
