Same as bug # 546. Fixed by rebuilding ncurses under glibc-2.0.108 (or fixing the compatibility code in glibc-2.0.108, since it obviously is quite broken :( ) Recompile ncurses against glibc2.1. Does that help? ncurses and/or readlne libs were not updated to relasess built against glibc 2.1. libio is not backwards compatible. Yet. |
I'm using glibc-2.0.108-0.981221, ncurses-4.2-11, egcs-1.1.1-2, and kernel 2.2.0-pre2. This simple ncurses program crashes: #include <ncurses.h> main() { initscr(); return 0; } "make menuconfig" in the Linux kernel also crashes for the exact same reason. Here's GDB output: Program terminated with signal 11, Segmentation fault. Reading symbols from /usr/lib/libncurses.so.4...done. Reading symbols from /lib/libc.so.6...done. Reading symbols from /lib/ld-linux.so.2...done. #0 0x400a821f in _IO_fflush (fp=0x401386c0) at iofflush.c:41 iofflush.c:41: No such file or directory.
