Qt4.8 to Qt5.1 sharedDLL

[ChrisW67]

is there something changed in Qt5.1 with shared library I should know about ?

Yes.
Deploying an Application on Windows: Creating the Application Package

doesn't seem much changed for deployment.

Further debugging, the "fatal error" occurs in the QT5Core.dll
GetProcAddress(0x77130000 [MSVCRT.DLL], "_get_output_format") called from "QT5CORE.DLL" at address 0x68A58EC9 and returned 0x771A5CE8.
Second chance exception 0xC0000005 (Access Violation) occurred in "QT5CORE.DLL" at address 0x688E2136.


but if i compile my DLL in Debug model, works fine !!

any tips why a DLL works fine in debug mode but not in Release ?

rgds,

[SOLVED]

I was declaring my class to access the DLL with " typedef __stdcall ", changing to typedef only fix the issue when compiling the .dll in release mode.
Not sure to understand why it made the calling function to crash, and why this is different from QT4.8 or GCC 4.7...

anyway.
