Hi I have an application which hangs after reading some lines from a file. It uses getc(). Upon attaching the process to gdb and checking the stack, it looks to be hanging at __read_nocancel(), like follows : (gdb) where #0 0x40000402 in __kernel_vsyscall () #1 0x00a3fe93 in __read_nocancel () from /lib/libc.so.6 #2 0x009e1d78 in _IO_file_read_internal () from /lib/libc.so.6 #3 0x009e30c0 in _IO_new_file_underflow () from /lib/libc.so.6 #4 0x009e37bb in _IO_default_uflow_internal () from /lib/libc.so.6 #5 0x009e4b1d in __uflow () from /lib/libc.so.6 #6 0x009dec10 in getc () from /lib/libc.so.6 #7 0x4000897f in syn_yylex () from /xalocal/L/lib/ldb/libsynL.so #8 0x4000fe89 in syn_yyparse () from /xalocal/L/lib/ldb/libsynL.so #9 0x40006141 in syn_check_syntax () from /xalocal/L/lib/ldb/libsynL.so #10 0x0804c1e8 in read_attr_syntax () #11 0x0804aa33 in proc_lines () #12 0x0804a213 in proc_ascii_file () #13 0x08049d99 in process_lf_request () #14 0x080496eb in process_args () #15 0x0804936c in main () Any ideas why this happens and how to get out of this? Thanks and Regards Vardhan
