ST_GeomFromGeoJSON() 导致 postgres 崩溃

Question

我遇到了一个我无法解决的奇怪问题。服务器在执行一些 postgis 相关查询时崩溃。一些调试后，使用实例 提供由PostGIS的，它出现在ST_GEOMFROMGeoJSON()函数引起服务器崩溃。

崩溃：

SELECT ST_AsText(ST_GeomFromGeoJSON('{"type":"Point","coordinates":[-48.23456,20.12345]}')) As wkt;

运行正常：

SELECT ST_AsText(
         ST_Transform(
               ST_GeomFromText('POLYGON((743238 2967416,743238 2967450,
                                         743265 2967450,743265.625 2967416,743238 2967416))',2249)
         ,4326)
        ) As wgs_geom; 

查看日志时，我发现这些条目与崩溃相关：

搜索网络并没有产生解决方案。也许我没有在寻找正确的问题？

我试图重新启动服务器，因为文件系统可能有一些故障，但没有结果。服务器本身是一台 Ubuntu 12.04 机器作为 VPS。postgresql 服务器是 9.3.5 和 Postgis 2.1.4

更新
Craig Ringer 建议我使用 gdb 来查看进程崩溃时会发生什么。这是第一个输出：

Program received signal SIGSEGV, Segmentation fault.
0xb70dda59 in _IO_vfprintf_internal (s=0xbfde7150, format=<optimized out>,  ap=0xbfde7298 "") at vfprintf.c:1630
1630    vfprintf.c: No such file or directory.

这也是输出postgis_full_verion()：

POSTGIS="2.1.4 r12966" GEOS="3.3.3-CAPI-1.7.4" PROJ="Rel. 4.7.1, 23 September 2009" 
GDAL="GDAL 1.9.0, released 2011/12/29" LIBXML="2.7.8" 
LIBJSON="UNKNOWN" TOPOLOGY RASTER

我说有什么不对vfprintf.c吗？例如它不存在？

它说 LIBJSON="UNKNOWN" 会产生影响吗？

我们崩溃问题的根源是库版本不匹配。构建系统使用的是 0.9，但我正在使用 0.11 的系统上进行部署。RPM 包仅将其要求声明为“json-c”，没有任何版本特异性。显然json 不向前二进制兼容，因此打包者要注意：您必须将 json-c 版本固定在包依赖项声明中。

Resolution set to invalid
Status changed from new to closed
Closing because this is a build problem.
