POSIX thread-safe application on Solaris 2.6

Hi, I wrote a client program that connect to Informix database using POSIX thread-safe library in SDK 2.40 on Solaris 2.6. I have no problems when compiling the code, but, got an error "Illegal Instruction (coredump)" when the program is run. The following is the details that I gathered from gdb. ------------------------------------------------------------------------ Details from gdb ------------------------------------------------------------------------ misssa$ gdb ./th-query GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
