Hi,
I am trying to debug a KLD using serial GDB but it keeps hanging..
ie I will enter the debugger OK, and generally everything will work OK
for a while, but then I'll want to do another command and it will just
sit there in the ttyin state :-/
It is sometimes recoverable but that requires

but I'm having trouble with some conversions from the Linux driver :)
In the Linux driver there is stuff like -

Hi,
WRT to Terry's email, I initialized the file by writing N nul ('\0')
bytes to it.

Hi,
Here are my test news. The -O bug doesn't happen with
gcc295 from ports !
I tried all these FLAGS, but noone of them was creating the
problems we see with -O :
Optimization Options
-fcaller-saves -fcse-follow-jumps -fcse-skip-blocks
-fdelayed-branch -felide-constructors
STABLE is broken too, but in a different manner. I just added -O and
then this happened.

I removed now #undef DEFAULT_VTABLE_THUNKS and set again #define
DWARF2_UNWIND_INFO 1 in the port. The -O tests still succeeded.
All cpp* files are the same in the port and our system compilers.
And ideas and pointers which subsystems I could test for this breakage ?

Exception-handling is broken with -O in -stable, and has been for years.
FreeBSD is one of the few systems that use setjmp/longjmp stack unwinds
to implement exceptions, so when the GCC folks broke that path, it was
never fixed. There are supposedly patches floating around that fix the
problem,

Easy to say, hard to do. STABLE is broken as current is, and it seems that
