--- Comment #4 from Ian Lance Taylor <ian at airs dot com> ---
Thanks for the file. Unfortunately it looks fine.
The error is coming from Import_function_body::read_type in
gcc/go/gofrontend/import.cc. At the point of the error this->body_ +
this->off_ points to a string starting with "<type 4>,". The function starts
like this:
this->require_c_string("<type ");
size_t start = this->off_;
size_t i;
int c = '\0';
for (i = start; i < this->body_.length(); ++i)
{
c = static_cast<unsigned char>(this->body_[i]);
if (c != '-' && (c < '0' || c > '9'))
break;
}
this->off_ = i + 1;
char *end;
long val = strtol(this->body_.substr(start, i - start).c_str(), &end, 10);
if (*end != '\0' || i > 0x7fffffff)
{
if (!this->saw_error_)
go_error_at(this->location(),
"invalid export data for %qs: expected integer at %lu",
this->name().c_str(),
static_cast<unsigned long>(start));
this->saw_error_ = true;
return Type::make_error_type();
}
It skips "<type ", leaving itself looking at "4>,". It steps past the "4".
Then it passes "4\0" to strtol. Somehow that is failing.
Since, needless to say, I can't reproduce the problem, do you have time to add
a bit of debugging around the strtol call, to see what is being passed and
returned?
