Public bug reported: Binary package hint: libcv2.1
This bug affects libcv2.1.0-2. Under certain circumstances, calling cvInvert causes a segmentation fault with the following stacktrace: Program received signal SIGSEGV, Segmentation fault. 0x03d36f4b in ATL_dgemvT_a1_x1_b0_y1 () from /usr/lib/libblas.so.3gf (gdb) bt #0 0x03d36f4b in ATL_dgemvT_a1_x1_b0_y1 () from /usr/lib/libblas.so.3gf #1 0x03d3169b in ATL_dgemv () from /usr/lib/libblas.so.3gf #2 0xbfffb504 in ?? () Backtrace stopped: previous frame inner to this frame (corrupt stack?) (gdb) quit This bug does not occur when compiling the package without the Ubuntu patches to opencv-2.1.0/src/cxcore/cxlapack.cpp. As cvCalibrateCamera* and cvFindChessboardCorners also call cvInvert, this may be the root of some other reported bugs as well. See also https://code.ros.org/trac/opencv/ticket/656 for a test program causing the bug. Note that this is NOT an upstream bug - compiling from opencv_2.1.0.orig.tar.gz without patches fixes this bug.
