Bug ID: 88482
Summary: ICE when wrongly declaring __cxa_allocate_exception
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rv at rasmusvillemoes dot dk
Target Milestone: ---
This causes an ICE:
#include <string>
extern "C" void __cxa_allocate_exception(std::size_t size);
int f(int x)
{
if (x > 27)
throw 19;
return x+3;
}
Changing to the correct "void*" works as expected. This is arguably a "Don't do
that then", but perhaps there's some simple way to turn the ICE into a more
explicit error, a la Werror=builtin-declaration-mismatch.
