Drawing 2D histogram from tree crashes root

AHoward · March 13, 2012, 4:29pm

Hi,
I have an issue whereby root crashes everytime I try and draw a 2D histogram from a TTree, but only if I do not redirect the output into a new histogram. So

T->Draw("A:B")

causes root to crash whereas

T->Draw("A:B>>()")

does not. The error message printed is

How about this? $\:D/$ { TFile *ff = new TFile("R123.root"); TTree *tt; ff->GetObject("RawData", tt); tt->Draw("xf:xr"); } Or perhaps this? <img src="/uploads/default/original/2X/8/84c2fe9464a4066c00e1bd5978e913e7869cbb07.gif" width=“22” height=“16” alt=":-"" title=“Whistle”/> { TFile *ff = new TFile("R123.root"); TTree *RawData; ff->GetObject("RawData", RawData); RawData->Draw("xf:xr"); } And maybe see this!

Hi Pepe,

Both of those variations lead to the same crash I’m afraid. Again, adding >>() in the draw command seems to circumvent the problem.

Thanks

Alan

Hi Alan,

This is quite strange. T->Draw("A:B>>()") because it is missing the histogram name leads to a crash (fixed today in revision 43348). However T->Draw(“A:B”) should not (and is pretty well tested as this is the general case. Can you run valgrind root.exe -l -q CrashTest.C and report the result? (Even better if you can run it with root.exe from the head of the trunk).

Thanks,
Philippe.

Hi Philippe,

Below is the output from valgrind using revision 43357. Due to the slowdown introduced by the debugger I can actually see the canvas being drawn and populated before the crash occurs now. As before, using the alternate draw command with >>() does not lead to a crash. I should also mention that I only began seeing this behaviour after moving to revision 43320. I don’t know which revision I was on previously, but it was at least several months older.

Hi Alan,

So the crux of the problem is:==3583== Invalid read of size 1 ==3583== at 0xC40D0EA: ??? (in /usr/lib/x86_64-linux-gnu/libX11.so.6.3.0) ==3583== by 0xC40D477: _XSetImage (in /usr/lib/x86_64-linux-gnu/libX11.so.6.3.0) ==3583== by 0xC40897B: XGetSubImage (in /usr/lib/x86_64-linux-gnu/libX11.so.6.3.0) ==3583== by 0xBD8743F: _ZL22XRotPaintAlignedStringP9_XDisplayP11XFontStructfmP4_XGCiiPcii.part.0 (in /usr/local/lib/root/libGX11.so) ==3583== by 0xBD885DE: XRotDrawAlignedString(_XDisplay*, XFontStruct*, float, unsigned long, _XGC*, int, int, char*, int) (in /usr/local/lib/root/libGX11.so) ==3583== by 0xBD8AFB7: TGX11::DrawText(int, int, float, float, char const*, TVirtualX::ETextMode) (in /usr/local/lib/root/libGX11.so) .... ==3583== Address 0x12a1d5e0 is 0 bytes inside a block of size 20 free'd ==3583== at 0x4C282E0: free (vg_replace_malloc.c:366) ==3583== by 0xBD861A2: MakeXImage(_XDisplay*, int, int) (in /usr/local/lib/root/libGX11.so) ==3583== by 0xBD873E6: _ZL22XRotPaintAlignedStringP9_XDisplayP11XFontStructfmP4_XGCiiPcii.part.0 (in /usr/local/lib/root/libGX11.so) ==3583== by 0xBD885DE: XRotDrawAlignedString(_XDisplay*, XFontStruct*, float, unsigned long, _XGC*, int, int, char*, int) (in /usr/local/lib/root/libGX11.so) ==3583== by 0xBD8AFB7: TGX11::DrawText(int, int, float, float, char const*, TVirtualX::ETextMode) (in /usr/local/lib/root/libGX11.so)which I do not see in my runs. So my best guess is either an issue with X11 and/or a mismatch between the X11 header and library.

Cheers,
Philippe.
