<p dir="auto">If this is still an issue, let's first investigate where exactly alloca() is used:</p>
<p dir="auto">Within lib/nettle, the two defines of TMP_ALLOC that use alloca() only use it if HAVE_ALLOCA is defined Please check if <code>config.h</code> contains <code>#define HAVE_ALLOCA 1</code>. If that is the case, we have to find out why the linker doesn't find alloca(). Possibly a library missing in a Makefile.am !?.</p>
<p dir="auto">If HAVE_ALLOCA is not defined in <code>config.h</code>, this is a gnulib issue and we should ask on the gnulib ML fro help.</p>

Those wrappings into TMP_ALLOC and TMP_DECL make technically not much sense in this code (except for obfuscation and saving a few bytes on the stack). There is no stack-reallocation needed since the array sizes are fixed-size or have a pretty low upper limit.</p>
