I'm encountering a really painful error. The stack trace is below.
The code in hash-table.h is a template and it is really hyper-allergic
to instrumentation (a couple of fprintfs caused malloc to have an
internal error!) Last time I checked gbd didn't exactly play nice
with templates either. Note, I tried adding --enable-checking=all to
my configure but all that did was cause a library installation failure.
If anybody has any clues about how to handle this kind of a bug or
even better yet if you have an a idea of what I did wrong then please
let me know.
Note, the particular optimization I'm working on is done at IPA time
and involve creating a bunce of gimple stmts, new types, new ssa temps
and changing the types of some existing declarations and ssa temps.
Thanks,
Gary
