Can cause csmReviveMocInPlace return nullptr when I use csmGetSizeofModel?
#include
#include
#include
int main(int argc,char ** argv)
{
for(auto i=0;i<100000;i++)
{
auto file = fopen("../../../CubismSDK/Core/Haru/Haru.moc3", "rb");
fseek(file, 0, SEEK_END);
auto len = ftell(file);
fseek(file, 0, SEEK_SET);
auto data = std::vector<uint8_t>(len);
auto readLen = fread(data.data(), sizeof(uint8_t), len, file);
if (len != readLen)
{
printf("No!");
}
auto moc = csmReviveMocInPlace(data.data(), len);
if (!moc)
{
printf("moc is nullptr!");
}
auto modelSize = csmGetSizeofModel(moc);
printf("%d\n", i);
fclose(file);
}
}
--------------------------------------------------------------------
I run my example.Not add csmGetSizeofModel's function can work.But I add csmGetSizeofModel will csmReviveMocInPlace return null and print my log "moc is nullptr!".

Please check if the allocated memory is alligned.
Here is Live2D Core API.
https://cubism.live2d.com/sdk-doc/reference/NativeCoreAPIReference_en_r11.pdf
And see the API 'csmReviveMocInPlace..."The address passed by address must satisfy the default alignment."
I wondered if perhaps the moc variable had an incorrect value because the memory was not aligned.
This is a sample to get alligned memory.

I try your example,it can work.
Thanks.
