Hi folks,
Steev has reported some crashing using ldconfig on arm64 systems with
armhf added as a secondary architecture - he's using this config in
Kali, for example.
Working through the problem with him on #debian-arm, I can see that
it's a problem with our/my patch for ARM ABI detection. On older
binaries that predate the new ABI flags in the ELF header, we're still
parsing the ARM attributes. That works fine on armel/armhf, but on
arm64 this code is being built wrongly using native (ELF64)
types. This patch is the obvious fix - enforce using ELF32 types for
all arches.
It seems that we still have some older packages without the ABI flags
attached - libshout3 is one such. :-(
