Bug ID: 167633
Summary: LibreOffice debug build crashed on launch when a Java
installation with a non-ASCII path is set during
configure(rtl_uString_newFromAscii(rtl_uString**,
const char*): Assertion `static_cast<unsig ned
char>(*pCharStr) < 0x80' failed.)
Product: LibreOffice
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice

Reporter: [email protected]
Description:
Encountered this crash on my development host, where I have a JDK installation
at ~/應用軟體/jdk24 (應用軟體 stands for "Applications").
This crash isn't produced on a release build, nor is it reproduced when I set
--with-jdk-home to /usr/lib/jvm, so the path seems to be hardcoded during build
configuration.
After attaching it to a debugger:

```
, I can pinpoint the exact function call that triggered the crash:
```c++
// desktop/unx/source/start.c
static void extend_library_path(const char *new_element)
{
rtl_uString *pEnvName=NULL, *pOrigEnvVar=NULL, *pNewEnvVar=NULL;
rtl_uString_newFromAscii(&pEnvName, "LD_LIBRARY_PATH");
rtl_uString_newFromAscii(&pNewEnvVar, new_element); // <- this one
...stripped...
}
```
It appears that the one who designs the logic wrongly assumes that the
LD_LIBRARY_PATH environment variable can only contain ASCII characters.
A patch has been made, stay tuned.
Steps to Reproduce:
1. Install a JDK under a non-ASCII path(e.g. ~/軟體/jdk-24).
2. Set JAVA_HOME and PATH environment variables to point to the JDK
installation ("~/軟體/jdk-24", and "~/軟體/jdk-24/bin").
3. Build LibreOffice with the `--with-dbgutil` configure option.
4. Run the `./instdir/program/soffice --writer` or `./instdir/program/oosplash`
command (./instdir/program/soffice.bin and ./instdir/program/soffice
--backtrace will _not_ work).
Actual Results:
No crash.
Expected Results:
The program aborted with the following error message:
```text
$ ./instdir/program/soffice
oosplash: /libo-core/sal/rtl/ustring.cxx:243: void
rtl_uString_newFromAscii(rtl_uString**, const char*): Assertion
`static_cast<unsigned char>(*pCharStr) < 0x80' failed.
Aborted (core dumped)
```
Reproducible: Always
User Profile Reset: Yes
