wxPGProp crash fix
Posted: Thu Nov 20, 2014 11:46 am
Hi Eran,
CL crashes on opening a project pref whose debugger entry can't be found, f.ex. when prefs had lldb stored, then are opened on a different PC where lldb isn't installed, wx ends up indexing an array with -1.
I'm pretty sure I saw similar crashes before when build configs across machines used different compiler names like "gcc49" vs "gcc-4.9" so I ended up patching wx, but recommend you use a wxProperty wrapper with an exception handler for release builds because wxproperty accessors return references.
thx & cheers,
