The behaviour under Windows XP is to assume in such a case that the size
is NOTIFYICONDATA_V1_SIZE. AFAIK Shell_NotifyIcon doesn't provide a way
to read icon data to check that the data introduced after Win95 is not
modified. So I'm using VirtualAlloc+VirtualProtect to make
Shell_NotifyIcon fail if it tries to access this data.
I'd like to catch the exception to make a tests fail if something goes
wrong instead of crashing the testsuite. However __try doesn't work
under gcc and using wine/exception.h gives an unresolved symbol
'__wine_handle_exception'. Is it possible to catch exceptions in tests?

#include "wine/exception.h"
__TRY
{
/* code that can segfault */
}
__EXCEPT_PAGE_FAULT
{
/* actions to take on segfault */
}
__ENDTRY
I'm not sure which library you have to link with.

Can we catch access violation exceptions in tests?
I'm trying to write a tests for invalid cbSize in Shell_NotifyIcon. The behaviour under Windows XP is to assume in such a case that the size is NOTIFYICONDATA_V1_SIZE. AFAIK Shell_NotifyIcon doesn't provide a way to read icon data to check that the data introduced after Win95 is not modified. So I'm using VirtualAlloc+VirtualProtect to make Shell_NotifyIcon fail if it tries to access this data.
