dwarf2-frame.c:1136: internal-error: Invalid or unsupported encoding
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) 

Is this PR1618?

Making libmy a shared library works fine.

No it isn't.  At least I think it isn't.  Please would you be so kind
to file a bug report for this one?

Can you find out what assembler are you using?

$ g++ -g -v static.cc -L. -my

should tell you what assembler GCC is using.

I think I know what the problem is, so you might see a fix soon.

Thanks,

Mark

We are using the Sun assembler, /usr/ccs/bin/as.
