dlopen crashes in 64bit mode
Hi,
I have 64bit C++ shared object built using Sun Fore Compiler(CC) on Solaris 9. However, when I try to open this shared object using dlopen on another Solaris 9 system, it crashes.
I am compiling my code on following system
SunOS 5.9 Generic_118558-30 sun4u sparc SUNW,Sun-Fire-880
and running it on
SunOS 5.9 Generic_118558-34 sun4u sparc SUNW,Sun-Fire-V440
Can any help me figure out what the problem is ?
I get the following in the crash log
Fault signal: SIGSEGV (11), address not mapped to object.
At instruction address 0xffffffff7e74f4a8, faulting access address is 0x61726377396fb9f8
Symbolic location: "realloc + 0x474 [/usr/lib/sparcv9/libc.so.1]"
Thanks in advance

Hi,
I have tried that option and I did get some information. After dlopen when I am trying to close using dlclose, the application is crashing. The log is given below.

Does this mean that there is a problem with the library /usr/lib/sparcv9/libc.so.1 or /usr/lib/sparcv9/libCstd.so.1 or any other library ?
Thanks in advance
