FFTW 2.1.5
Posted: July 30 2005
Hi Folks,
Has anybody ever run into problems with seg faults in FFTW when handling moderately large arrays? Im having a weird time with it recently - getting seg faults when passing
rfftw_create_plan((int)nsamp,FFTW_REAL_TO_COMPLEX,FFTW_ESTIMATE);
with nsmap >= 2^19 . Its not a memory thing, and it's repeatable on at least three different platforms. Its definately isolated to the create_plan call. hoping not to have to port to v3 ...
Thanks,
-Bill
