Bug ID: 264979
Summary: archivers/c-blosc2: compiler crash on armv7
Product: Ports & Packages
Version: Latest
Hardware: arm
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: Individual Port(s)

Flags: maintainer-feedback?(sunpoet@FreeBSD.org)
Building this port causes a compiler crash on armv7. The crash has been
reduced with creduce to the following minimal test case:
extern int a, d, i[], e[];
_Noreturn int c(void);
void f()
{
d <= 3 ? 0 : c();
for (int h = 1; h < d; ++h)
i[h] = a % e[h - 1] / e[h];
}
The crash is due to a SIGBUS (unaligned memory access?) and might be the same
thing that happened on PPC64 (pkubaj@, please check). I'll go ahead and report
it with upstream.
As a stop gap measure, the port should be compiled with gcc on armv7, too.
