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
