libstdc++ core dump


Hi -

Issue was found on RedHat, SuSe ES 9 and 10 Linux Platform

We have 2 different products. They both work perfect independently.
But when product1 loads product2 Shared library, everything goes wrong. core dump happens to be in libstdc++.

Product1 is using STLport while Product2 is using Native STL libstd++ library.

I want to check thread-safety of each and every library and binary of both products. Is there a tool on Linux similar to "footprints" on HPUX, which dumps compiler/linker options.

"footprints" on hp-ux can dump compiler options of the binary.

I tried objdump/nm but don't know how to check thread-safety of particular library.

core dump stack trace.
