Please remember to assign keywords to bug reports. To everybody reading this:
Please look through issues you've reported and check for missing keywords.
Also, please avoid vague summary lines that could equally apply to many
unrelated bugs. As a guide, if there exists a keyword that says what your
summary says, then the summary is too vague.

Ok. Could the bugzilla ugliness be modified so that there is a combo from which
to select keywords? I keep forgetting their spelling.
I have changed the summary because the compiler crashes when the template is
parametrized with any tuple containing more than one element.

I keep forgetting their spelling.Really, a <select multiple> is what we want. I don't know whether there's an option in Bugzilla to do this, but it could probably be done by hacking the local installation. That said, the version of Bugzilla we're using here is far from current, so FAIK the best COA might be to upgrade. --

This is actually really simple.
ROOT CAUSE: The D1 logic in template.c,
TemplateDeclaration::deduceFunctionTemplateMatch() is completely wrong.
if (nargsi > parameters->dim) && tp, the assert in the for loop will definitely
fail.
PATCH (around line 797 of template.c):
==========
if (targsi)
{ // Set initial template arguments
nargsi = targsi->dim;
+ size_t argsToUse = nargsi;
if (nargsi > parameters->dim)
{ if (!tp)
goto Lnomatch;
dedargs->setDim(nargsi);
dedargs->zero();
+ argsToUse = parameters->dim;
}
memcpy(dedargs->data, targsi->data, nargsi * sizeof(*dedargs->data));
- for (size_t i = 0; i < nargsi; i++)
+ for (size_t i = 0; i < argsToUse; i++)
{ assert(i < parameters->dim);
This patch also fixes bug 1897.

The patch for this bug was incorrectly transcribed.
template.c, line 807.
- memcpy(dedargs->data, targsi->data, n * sizeof(*dedargs->data));
+ memcpy(dedargs->data, targsi->data, nargsi * sizeof(*dedargs->data));
This is causing dstress case for bug 1144 to fail.
