[Bug]: 32-bit ARM build of openjdk-25 has Illegal instruction (also, unpatched TMP_BUFFER_LEN discovered) #27045
Description
Problem description
Unfortunately, for some reason only beginning with openjdk-25 and only with the 32-bit ARM build, an Illegal instruction error is occurring whenever the java command is run.
~ $ $PREFIX/lib/jvm/java-25-openjdk/bin/java
Illegal instruction $PREFIX/lib/jvm/java-25-openjdk/bin/java
~ $
Creating and using a temporary debugging build causes the Illegal instruction error to turn into this more detailed Assertion Failed error:
[error occurred during error reporting (), id 0xe0000000, Internal Error (/home/builder/.termux-build/openjdk-25/src/src/hotspot/share/runtime/thread.hpp:660)]
#
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (/home/builder/.termux-build/openjdk-25/src/src/hotspot/os/posix/perfMemory_posix.cpp:141), pid=911, tid=912
# assert(strlen(tmpdir) == 4) failed: No longer using /tmp - update buffer size
#
# JRE version: (25.0.1) (slowdebug build )
# Java VM: OpenJDK Server VM (slowdebug 25.0.1, mixed mode, sharing, g1 gc, linux-arm)
# Problematic frame:
# V [libjvm.so+0xaef4fc]
#
# Core dump will be written. Default location: /data/data/com.termux/files/home/core.911
#
What steps will reproduce the bug?
# 32-bit ARM
pkg upgrade
pkg install openjdk-25
$PREFIX/lib/jvm/java-25-openjdk/bin/javaWhat is the expected behavior?
Usage: java [java options...] <application> [application arguments...]
Where <application> is one of:
<mainclass> to execute the main method of a compiled main class
-jar <jarfile>.jar to execute the main class of a JAR archive
-m <module>[/<mainclass>] to execute the main class of a module
<sourcefile>.java to compile and execute a source-file program
Where key java options include:
--class-path <class path>
where <class path> is a list of directories and JAR archives to search for class files, separated by ":"
--module-path <module path>
where <module path> is a list of directories and JAR archives to search for modules, separated by ":"
-version
to print product version to the error stream and exit
For additional help on usage: java --help
For an interactive Java environment: jshell
