POProgram crash in x64, works fine in Win32
text
Body
copied!<p>I'm working on an application which builds and runs fine in Win32. However, in x64, it builds but crashes on run. Looking at the code and narrowing down the problem, if I comment out the call to the below function, it runs with no problem.</p> <pre><code>void vec3_copy (double* v1, const double* v2) { v1[0] = v2[0]; v1[1] = v2[1]; v1[2] = v2[2]; } </code></pre> <p>I'm building in Visual Studio 2008 with the C/C++ compiler. All updates have been installed. Any ideas?</p> <p>EDIT 1 (to answer comments):</p> <p>The pointers should be valid, as in Win32, it runs fine. No code is change and a different path is not taken, unless the pointer are somewhat modified because its x64 (will look into this).</p> <p>Unfortunately, there is no information about the crash. In Windows 7, it simply saying that it is looking for a solution to the problem, finds nothing, and returns in the command prompt. In the event viewer, I was able to find the following information:</p> <pre><code>Faulting application name: DRR_C.exe, version: 0.0.0.0, time stamp: 0x4b7a1ee1 Faulting module name: DRR_C.exe, version: 0.0.0.0, time stamp: 0x4b7a1ee1 Exception code: 0xc0000005 Fault offset: 0x0000000000003950 Faulting process id: 0x16a4 Faulting application start time: 0x01caaec078a9c84a Faulting application path: D:\Development\gpu\dev\DRR_C\x64\Debug\DRR_C.exe Faulting module path: D:\Development\gpu\dev\DRR_C\x64\Debug\DRR_C.exe </code></pre> <p>EDIT 2 (to answer more comments):</p> <p>Modified the line to,</p> <pre><code>memcpy(v1, v2, 3 * sizeof(double)); </code></pre> <p>New error info has the same exception code and fault offset.</p>
