#5987 closed defect (fixed)

Crash with gdal_grid on 64bit when AVX compile time enabled

Reported by: Even Rouault Owned by: warmerdam
Priority: normal Milestone: 1.11.3
Component: default Version: unspecified
Severity: normal Keywords:


With some compilers (e.g. GCC 4.4), in -O2 mode, when AVX is available at compile time (not necessarily at runtime), the current implementation of GCC_CPUID zeroes the upper 32 bits of the %rbx register, causing crashes in some circumstances.
