Problem with gcc -pg

[Rajeskhar Bhattacharjee]

Hello,

I have a problem  using profiling on solaris 8 using gcc. When I compile
a small test program
with gcc -g -pg, it compiles and runs correctly. However, when I build
my main application
using the same flags at the compilationa and likning steps, the build
completes successfully but
the application gives a segemntation fault. Is it a bug? Does gcc have a
problem profiling in
presence of threads or shared libs?

Thanks in advance,
