#90 Many samples crash

[Henk-Jan van Tuyl]

Many of the wxHaskell program samples crash, for example:

[...]\wxHaskell\samples\wxcore>ImageViewer.exe
Segmentation fault/access violation in generated code

(the message is always the same)

Versions:

Item	Version
OS	Windows XP, Windows 8.1
GHC	7.6.3
wxWidgets	2.9.5
wxHaskell	0.91.0.0 (currently in GitHub repository)
GCC	4.5.2

[Henk-Jan van Tuyl]

With wxWidgets 3.0.1, most crashes have disappeared; the only crashing sample programs are now:

• wx/Print.hs (when selecting a menu item)
• wx/TestTaskBarIcon.hs (when the program is terminated)

(Testing is done on a Windows 8.1 system)

[Henk-Jan van Tuyl]

The crashes returned at some point, but most are solved by removing the double initiation of the image handlers and the new procedure to compile wxWidgets, which ensures that the compiler used for wxWidgets is identical to the one used for installing wxHaskell. See https://wiki.haskell.org/WxHaskell/Windows#wxWidgets_3.0_and_wxHaskell_.3E.3D_0.92

[Henk-Jan van Tuyl]

Crashes are very rare now; report crashes in seperate tickets.
Current configuration:

Item	Version
Windows	8.1
GHC	7.10.2
wxWidgets	3.0.2
wxHaskell	0.92.0.0 (currently in GitHub repository)
GCC	4.6.3

(GHC 7.10.1 made all wxHaskell software crash)
