Hi Dave,
We've recently seen lcrash fail with a floating point exception
very early in initialization.
Seems to be a binary compiled under one distribution and then
executed on another.
And the solution seems to be the -Wl,--hash-style=both option.
Have others reported this?
This isn't specific to crash; it's the result of a change in the
Linux/glibc ABI. Specifically, the new ABI has a .hash.gnu section
whereas the old one has .hash. Your linker option above causes both
sections to be included, so that the old dynamic loader can load a
binary built with a new toolchain.
