bjam crashes on QNX 6.4.0

Reported by: Niklas Angare <li51ckf02@…> Owned by: René Rivera
Milestone: Boost.Jam 3.1.17 Component: bjam
Version: Boost.Jam 3.1.16 Severity: Showstopper
Keywords: Cc:

Description

'make install' for Boost fails on QNX 6.4.0 because bjam crashes. QNX 6.4.0 uses gcc 4.2.4 whereas QNX 6.3.2 used gcc 3.3.5.

The solution is to add "-Wc,-fno-strict-aliasing" for the qcc toolset in tools/jam/src/build.jam (line 257), just like the gcc toolset has -fno-strict-aliasing.

The first crash happens because the compiler optimizes away zeroing of fields in file_info() in tools/jam/src/filesys.c.

The patch I attached has been tested against the final 1.37.0. With it, bjam no longer crashes and many libraries build successfully.

Milestone: Boost 1.37.0 → Boost.Jam 3.1.17
Version: Boost Release Branch → Boost.Jam 3.1.16

Resolution: → fixed
Status: new → closed

(In [49889]) Add -Wc,-fno-strict-aliasing for QCC/QNX to avoid the same aliasing crashes as in the general GCC 4.x series (thanks to Niklas Angare for the fix). (fixes #2459)
