122 Extracting the tarball
123 will reset the permissions of the current directory to 0755 if you
124 have permission to do that. If you do this in a directory where
125 the sticky bit is set, such
126 as <filename class="directory">/tmp</filename> it will end with error
127 messages:

179 To run JS test suite, issue:
180 <command>make -C js/src check-jstests
181 JSTESTS_EXTRA_ARGS="--timeout 300 --wpt=disabled"</command>.
182 It's recommended to redirect the output into a log.
183 <!-- recheck when ICU gets upgraded -->
184 <!-- ken: removed "are known to fail' becasue there are
185 4096 known failures, these icu items are unexpected failures
186 and I found the wording confusing -->
187 <!-- ken : For 78.4 this was 14 failures, I changed it to 10 for 78.5.
188 On that machine with 78.6 still 10, but on another 14, both with similar
189 setup and locale. -->
190 Depending on the machine, either
191 ten or fourteen JS tests related to locale and timezone fail,
192 because of an issue in <xref linkend="icu"/>.
193 To run the JIT test suite, issue:
194 <command>make -C js/src check-jit-test
195 JITTEST_EXTRA_ARGS="--timeout 300"</command>. Again, a few tests
196 may show as unexpected failures.

201 An issue in the installation process causes any running program which
202 links to JS78 shared library (for example, GNOME Shell) to crash if
203 JS78 is upgraded or reinstalled. To work around this issue, remove
204 the old version of the JS78 shared library before installation:

243 <para>
244 <parameter>--disable-jemalloc</parameter>: This switch disables the
245 internal memory allocator used in JS78. jemalloc is only intended for
246 the Firefox browser environment. For other applications using JS78,
247 if JS78 uses jemalloc, the application may crash as items allocated
248 in jemalloc allocator are freed on system (glibc) allocator.

251 <para>
252 <parameter>--disable-debug-symbols</parameter>: Don't generate debug
253 symbols since they are very large and most users won't need it. Remove
254 it if you want to debug JS78.
