I am using TEXstudio heavily -several hours per day on Airbook under MacOs 10.7.4. Unfortunately, it often (once per 1-2 hours) happens that the system crashes by referring to SIGSEGV error - quite unexpectedly during the work, i.e. editing source text with frequent Cmd C, X, V use, repeated
compiling (using pdflatex) and switching from source to pdfviewer and back.

## Discussion

• which version of txs are you using ?
Do you get a backtrace on the crashes ?

I am using TEXstudio 2.4. Backtrack is difficult to obtain since the crash is quite unexpected
during the work. But I will try when it again occurs.

• are you able to compile txs yourself and let it run in a debugger ?

• It is supposed to create files like /tmp/texstudio_backtrace*.txt, when
a SIGSEGV occurs.

(although I don't know how to convert the addresses from that file in
usable function names, without having a mac debug version )

Unfortunately, I do not have programming tools on my Airbook, I am pure Latex user. Anyway, when the error occurs, I will try to get some kind of backtrace. Yesterday, it happened 3 times, today not yet.

Hello, today TEXstudio crashed again. Unfortunately, I was unable to obtain some memory log, but the trace was as follows:
1. I have altogether 5 opened files, 4 tex + 1 bib
2. I copied about 100 lines from one tex file to another one on which I am currently working.
3. I ran PdfLatex (TEXLive) on the current file. The compilation was OK and I switched then to the internal PDF viewer.
4. I switched from PDF viewer back to the source file using cmd' .
5. I moved through the source file using the down arrow and the system suddenly crashed by the SIGSEGV error.

• is the crash reproducible ? (at the exact same point ?)

Hello, today Texstudio crashed 2 times on the same file. I had 4 files open. When opening the 5th one (attached), Texstudio crashed, fell into a loop and I had to invoke force quit. Then I opened it again. Texstudio did not crash immediately as in the first time. However, I first
copied the whole file into another file with which I am currently working and then I deleted from this included file all the introductory lines begining with \documentclass until abstract - and then the crash occurred again.

• there is no file attached.
can you send it by mail ?
