You did not specify which GIT version, but I will hazard a guess: gp-git48332bc.exe but 48332bc is not the latest git (48332bc is from Wed May 2) Unfortunately, gp-gitd1d257d.exe did not pass the test suite, so was not put on the server. I just added it. Please check it. Under wine it does not exhibit this problem. Now, the test-cyclo bug: On linux 32bit without GMP, the stack is set to 4MB. and the 'portable' FFT code use more PARI stack than the GMP FFT code (which use malloc instead), so the stack overflow only on 32bit/without GMP. Cheers, Bill.
