bug in atof
by Louis. Lenders Jan. 22, 2006

Jan. 22, 2006

Hi, i filed a bug ( bug 4337) and looks like there's a bug in atof. Is there a difference between linux' atof and msvcrt's one? Even following simple program (from msdn) yields wrong results: // crt_atof.c #include <stdlib.h> #include <stdio.h> int main( void ) { char *s; double x; int i; long l; s = " -2309.12E-15"; /* Test of atof */ x = atof( s ); printf( "atof test: \"%s\"; float: %e\n", s, x ); s = "7.8912654773d210"; /* Test of atof */ x = atof( s ); printf( "atof test: \"%s\"; float: %e\n", s, x ); s = " -9885 pigs"; /* Test of atoi */ i = atoi( s ); printf( "atoi test: \"%s\"; integer: %d\n", s, i ); s = "98854 dollars"; /* Test of atol */ l = atol( s ); printf( "atol test: \"%s\"; long: %ld\n", s, l ); } the exponent value in float x are wrong.

Threading performance
by Evil Jan. 22, 2006

Jan. 22, 2006

Hi all, I was just playing around with the Video Stress Test in CounterStrike: Source, and noted a lot of odd stuttering. The demo would run for about 15 seconds at 13fps, then completely freeze up for about 15 seconds. Then, it would start running again... only to freeze/unfreeze every 15 seconds or so. Just for fun, I reniced all the wine processes down to +15. The result: the demo runs completely smooth (well, at 13fps... but that's on account of my low system specs) from start to finish. I did some searching and noticed a similar report last year: http://www.winehq.com/hypermail/wine-devel/2004/08/0306.html I wasn't having this problem last year, but I've updated so many things in the last month (like moving from KDE3.4 to KDE3.5, and updating WINE from CVS), so I'm afraid I can't pinpoint the exact cause right now. Does anyone know of another, more permanent, workaround rather than re-nicing after starting WINE? Is there anything I can do/test that might help the developers if this is a real threading issue? -J AMD AthlonXP 2000+ ATI 9600XT w/128MB 1GB System RAM Mandriva 2006.0, updated to KDE3.5

Dreamcom Kubik SMS crash
by Pavel Troller Jan. 22, 2006

Jan. 22, 2006

Hi, all the wine developers, thanks for wine, it's going to be really powerful now! However, even the most recent CVS update from yesterday still fails to run a small SMS sending program called Kubik SMS from DreamCom. This program can be freely downloaded: http://ww.dreamcom.cz/dream556.zip Program now installs smoothly, including Mozilla ActiveX Control (thanks for using the repackaged ReactOS version). However, after trying to run the program, the following crash appears: patrol(a)arcus:/opt/samba-dir/DreamCom$ wine DreamCom.exe fixme:ole:CoResumeClassObjects stub fixme:wininet:InternetGetConnectedState always returning LAN connection. wine: Unhandled exception 0x0eedfade at address 0x0000:0x7b83f040 (thread 0009), starting debugger...

I already have it installed, but I wasn't sure it would work very nicely, though. I was afraid there would be too much pointless output to wade through, but I'll try it tomorrow sometime.

winedbg symbols completely screwed
by Christer Palm Jan. 21, 2006

Jan. 21, 2006

Continuing my debugging efforts, I decided to look some more at the strange symbols I got in the backtrace. Indeed, it seems like winedbg completely screws up the MFC42 symbols. For example, by disassembling from the load address of MFC42 I was able to identify the CString::FreeData() function at 0x5f402125, but winedbg tells me it's 0x5f445900. Is this a known problem?
