Hi,

I had printed the value of the handle. The result is given below :

Calling dlclose , handle is : 0x7d4014c8

Fault signal: SIGBUS (10), invalid address alignment.
At instruction address 0xffffffff7e64f4a8, faulting access address is 0x4e5352532eb267cc
Symbolic location: "realloc + 0x474 [/usr/lib/sparcv9/libc.so.1]"

------ Concluding frames leaf call (n=1) ------
# 0 0x7e64f4a8 realloc + 0x474 [/usr/lib/sparcv9/libc.so.1]
[0x1,0x1f3920,0x1,0x1f3920,0x1,....]
# 1 0x7e64f444 realloc + 0x410 [/usr/lib/sparcv9/libc.so.1]

How do I find if the handle is corrupted or not ? Also, the program runs fine on some systems , on only on a few systems it crashes ??
