Segmentation fault in vorbis_analysis_wrote on Windows #117
Description
Hello, I've noticed a segmentation fault inside vorbis_analysis_wrote, here is a minimal reproducible example
// test.cpp
// compiled with: clang++ test.cpp -o test.exe -lvorbis -lvorbisenc
#include <vorbis/vorbisenc.h>
int main() {
const int size = 260000; // 250000 will be ok
vorbis_info vi;
vorbis_dsp_state vd;
vorbis_info_init(&vi);
vorbis_encode_init_vbr(&vi, 2, 44100, 0.5f);
vorbis_analysis_init(&vd, &vi);
float** buffer = vorbis_analysis_buffer(&vd, size);
vorbis_analysis_wrote(&vd, size); // seg faults here
vorbis_dsp_clear(&vd);
vorbis_info_clear(&vi);
return 0;
}I've tried to use gdb, and the backtrace is like below
