Description Michael Stahl 2016-07-07 11:00:06 UTC

Description of problem:
During debugging, if an inferior gets a SIGSEGV, the execution cannot be continued, the continue always results in pausing with the same SIGSEGV being reported.

Version-Release number of selected component (if applicable):
qt-creator-4.0.2-1.fc24.x86_64
qt-creator-data-4.0.2-1.fc24.noarch

How reproducible:
always

Steps to Reproduce:
1. make sure you have LO WikiPublisher installed, dnf install libreoffice-wiki-publisher
2. QtCreator: Debug->Attach to running Application, soffice.bin
3. in LO, create new writer document
4. (in case this doesn't yet result in a SIGSEGV, "File->Send->To MediaWiki..."
5. QtCreator stops with "Signal Received: SIGSEGV" - stack shows weird JVM stuff
6. click "continue"

Actual results:
7. goto 5.

Expected results:
the debugger should not break again for the same signal if "continue" is clicked.

Additional info:
it is apparently perfectly normal that JVM startup produces one or two SIGSEGV
so it's very inconvenient if that breaks the debugging experience.

was thinking of reporting this upstream but don't have a lawyer handy to explain the legal agreement one is required to accept before filing Qt bugs.

@Michael Stahl
Upstream asks: "What happens when using plain GDB in this case?"

Comment 2 Michael Stahl 2016-07-11 11:12:43 UTC

"c" works well in plain gdb with the default settings.

(gdb) info signal 11
Signal        Stop      Print   Pass to program Description
SIGSEGV       Yes       Yes     Yes             Segmentation fault

F24's KDevelop can also continue in this case.

can't try F24's Eclipse because it (or rather gdb run in it) has a more serious issue, but in F23 the Eclipse CDT had no problem doing this.

Please try [1] which contains upstream patch candidate [2].
