Hi,

I just found a bug in the CDDA implementation on Mac. Actually, it’s reproducable on PPC and Intel Macs.

It crashes with these outputs in XCode:
[code:172aomto]
0x09eb6184 <+6524> stwu r1,-112(r1)
0x09eb6188 <+6528> mr r29,r4
0x09eb618c <+6532> lwz r0,228(r3)
0x09eb6190 <+6536> mr r27,r5
0x09eb6194 <+6540> cmpw cr7,r4,r0
0x09eb6198 <+6544> li r0,36

0x09eb61b0 <+6568> stw r4,232(r30)
0x09eb61b4 <+6572> mr r3,r28

0x09eb61c0 <+6584> bne- 0x9eb6210 <_ZN4FMOD7ReverbID1Ev+6664>
[/code:172aomto]

What do I do? I do many readData calls to a subsound of the CD (some kind of prebuffering). It actually, crashes sometimes but in my case almost every second time.

Can you show us the code that causes the problem?

Hi andrew,

actually, I cann’t give you some small source code that’s producing this error. It occours only in our main application in connection with cdda decoding. I’ll do my best to write a small example that’s reproducing this issue. Actually, I am not quite sure if I get it to crash without that much interaction like in my main application.

with kind regards
slajar
