[tor/release-0.2.7] Fix backtrace compilation on FreeBSD
by nickm＠torproject.org 16 Dec '15

16 Dec '15

commit 07cca627eaab800d4874f3d0914d3cf7eaa601a9 Author: cypherpunks <cypherpunks(a)torproject.org> Date: Tue Dec 15 16:30:04 2015 +0100 Fix backtrace compilation on FreeBSD On FreeBSD backtrace(3) uses size_t instead of int (as glibc does). This causes integer precision loss errors when we used int to store its results. The issue is fixed by using size_t to store the results of backtrace(3). The manual page of glibc does not mention that backtrace(3) returns negative values. Therefore, no unsigned integer wrapping occurs when its result is stored in an unsigned data type. --- changes/bug17827 | 3 +++ src/common/backtrace.c | 16 ++++++++-------- src/common/backtrace.h | 2 +- src/common/sandbox.c | 2 +- 4 files changed, 13 insertions(+), 10 deletions(-) diff --git a/changes/bug17827 b/changes/bug17827 new file mode 100644 index 0000000..04cd3b5 --- /dev/null +++ b/changes/bug17827 @@ -0,0 +1,3 @@ + o Minor bugfixes (compilation): + - Fix backtrace compilation on FreeBSD.
