* 3.5.1 (February 25, 2014)
|
||||
|
||||
This version primarily addresses minor bugs in test code.
|
||||
|
||||
Bug fixes:
|
||||
- Configure Solaris/Illumos to use MADV_FREE.
|
||||
- Fix junk filling for mremap(2)-based huge reallocation. This is only
|
||||
relevant if configuring with the --enable-mremap option specified.
|
||||
- Avoid compilation failure if 'restrict' C99 keyword is not supported by the
|
||||
compiler.
|
||||
- Add a configure test for SSE2 rather than assuming it is usable on i686
|
||||
systems. This fixes test compilation errors, especially on 32-bit Linux
|
||||
systems.
|
||||
- Fix mallctl argument size mismatches (size_t vs. uint64_t) in the stats unit
|
||||
test.
|
||||
- Fix/remove flawed alignment-related overflow tests.
|
||||
- Prevent compiler optimizations that could change backtraces in the
|
||||
prof_accum unit test.
