I found suspicious difference between the working build and the not-working build. The not-working build has fflush.o, fseek.o and fseeko.o in build/libgnu/.libs directory, while the working build does not. Also, cygoctave-7.dll of not-working build exports rpl_fflush, rpl_fseek and rpl_fseeko, while that of the working build does not. As a test, I used following patch to forcibly remove the code setting REPLACE_FSEEKO to 1 in configure script, and rebuilt octave. This works without segmentation fault. I do not look into the reason why this difference causes yet. I would be happy if this could help. --- m4/fseeko.m4.orig 2020-01-29 21:39:37.280507900 +0900 +++ m4/fseeko.m4 2020-01-29 21:36:29.263747100 +0900 @@ -30,16 +30,19 @@ HAVE_FSEEKO=0 else if test $WINDOWS_64_BIT_OFF_T = 1; then - REPLACE_FSEEKO=1 + dnl REPLACE_FSEEKO=1 + REPLACE_FSEEKO=0 fi if test $gl_cv_var_stdin_large_offset = no; then - REPLACE_FSEEKO=1 + dnl REPLACE_FSEEKO=1 + REPLACE_FSEEKO=0 fi m4_ifdef([gl_FUNC_FFLUSH_STDIN], [ gl_FUNC_FFLUSH_STDIN case "$gl_cv_func_fflush_stdin" in *yes) ;; - *) REPLACE_FSEEKO=1 ;; + dnl *) REPLACE_FSEEKO=1 ;; + *) REPLACE_FSEEKO=0 ;; esac ]) fi --- m4/fflush.m4.orig 2020-01-29 21:40:07.546238000 +0900 +++ m4/fflush.m4 2020-01-29 21:38:02.079793700 +0900 @@ -16,7 +16,8 @@ gl_FUNC_FFLUSH_STDIN case "$gl_cv_func_fflush_stdin" in *yes) ;; - *) REPLACE_FFLUSH=1 ;; + dnl *) REPLACE_FFLUSH=1 ;; + *) REPLACE_FFLUSH=0 ;; esac ]) -- Takashi Yano -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
