[Bug 14393] New: atoi() implemenation on large integers is wrong
http://bugs.winehq.org/show_bug.cgi?id=14393 Summary: atoi() implemenation on large integers is wrong Product: Wine Version: 1.1.0 Platform: Other OS/Version: other Status: UNCONFIRMED Severity: minor Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: shino(a)jenux.homelinux.org CC: shino(a)jenux.homelinux.org Created an attachment (id=14706) --> (http://bugs.winehq.org/attachment.cgi?id=14706) demonstration of the wrong behaviour This bug has been mentioned on the wine mailinglist: http://www.winehq.org/pipermail/wine-devel/2004-May/027187.html If you give atoi a string of an unsigned integer (>2^31) the wine implementation gives a strange result (apparently alway the same integer). The GNU-libc and the windows implementation gives the correct, unsigned integer. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Anyway, mingw&wine gives other results than mingw&windows - it may cause hard-to-find bugs if applications rely on the windows-specific behaviour. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Are you testing on 64-bit Windows as well? -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

The executable you built uses glibc and therefore you get this result. Your application won't run without cygwin, or at least, without the 'cygwin.dll'. You can tell gcc that you don't want to build a cygwin exectuable but a native windows appliction by adding the '-mno-cygwin' parameter. So compile the source like this: 'gcc foo.c -mno-cygwin -lwsock32', run the resulting exe and you'll see the difference. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
