a symbol matches multiple clauses the last one takes precedence. If the catch-all is last it captures everything. In the case of Qt5 libraries this caused all symbols to have a Qt_5 label while some should have Qt_5_PRIVATE_API. This only affects lld because GNU ld always gives the catch-all lowest priority. Older versions of Qt5Webengine exported some memory allocation symbols from the bundled Chromium. Version 5.9 stopped exporting these [1] but the symbols were kept as weak wrappers for the standard allocation functions to maintain binary compatibility. [2][3] The problem is that the call to the standard function in these weak wrappers is only resolved to the standard function if there's a call to this standard function in other parts of Qt5Webengine, because only then is there a non-weak symbol that takes precedence over the weak one. If there's no such non-weak symbol the call in the weak wrapper resolves to the weak wrapper itself creating an infinite call loop that overflows the stack and causes a crash. Some of the allocation functions are variants of C++ new and delete and it probably depends on the compiler whether these variants are used in other parts of Qt5Webengine. Remove the weak wrappers (make them Linux specific). This isn't binary compatible but we are already breaking that with the changes to the symbol versions. [1] |

This is the FreeBSD Ports Collection. For an easy to use WEB-based interface to it, please see: https://www.FreeBSD.org/ports For general information on the Ports Collection, please see the FreeBSD Handbook ports section which is available from: https://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/ports.html for the latest official version or: The ports(7) manual page (man ports). These will explain how to use ports and packages. If you would like to search for a port, you can do so easily by saying (in /usr/ports): make search name="<name>" or: make search key="<keyword>" which will generate a list of all ports matching <name> or <keyword>. make search also supports wildcards, such as: make search name="gtk*" For information about contributing to FreeBSD ports, please see the Porter's Handbook, available at: https://www.FreeBSD.org/doc/en_US.ISO8859-1/books/porters-handbook/ NOTE: This tree will GROW significantly in size during normal usage! The distribution tar files can and do accumulate in /usr/ports/distfiles, and the individual ports will also use up lots of space in their work subdirectories unless you remember to "make clean" after you're done building a given port. /usr/ports/distfiles can also be periodically cleaned without ill-effect.
