Summary: riched32 dereferences null pointer from WASTE
Product: Wine
Version: 20041201
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: major
Priority: P2
Component: wine-winelib
AssignedTo: wine-bugs at winehq.org
ReportedBy: aerowolf at gmail.com
Hi, I just ported WASTE 1.0b to winelib. It is unstable without native DLLs:
type 1 line, it shows up fine.
type 2 lines, they show up.
type 3 lines, the first two disappear.
type more than 3, all lines disappear. Until you get to 7 or 8, at which point
the first line shows up again in the middle of the richedit box, and eventually
all the other lines show up.
When you try to select any of the text, and copy it to the clipboard, it
triggers a catastrophic failure:
wine: Unhandled exception (thread 0009), starting debugger...
WineDbg starting on pid 0x8
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code
(0x1028114b).
In 32 bit mode.

This is the Fedora Core 3 RPM release of 01Dec2004. There is no older (i.e.,
riched20) implementation I can otherwise use.
