I am using vtl to do some hotspot analysis. For one of my application, the data collection phase was fine; but when I want to view the result (using "vtl view"), I got hundreds of lines of "Warning - runnning *really* short on DMA buffer", followed by the following message:
sfdump5: QAlloc.c: 351: void *OurMalloc(unsigned int): Assertion 'mT->allocedArray.mem != __null' failed.
I did check with "vtl show" and a result was listed there. The collector I used was "sampling". Simple applications, such as "/bin/ls", worked just fine.
