It is probably either a bug in uClibc, a disabled option that should
be enabled, or a stripped library that should be unstripped.  You're
going to have to follow a debugger into libthread_db to see what is
causing the "generic error" message.

Correct.

General rule: never use "handle SIG32 nostop" or "handle SIGTRAP
nostop".  They are workarounds for configuration problems, and the
problems will come back and bite you again if you don't fix them.
