Hi,
I am creating 32-bit application on RHEL4 x86_64. Simple 32-bit
hello worlds work fine. However, when running a slightly more
complicated example which depends on a 32-bit .so, I get the
following system error when I run the application under gdb ( or by
itself outside of gdb)
This must be a pretty common issue, but I am a bit baffled.
